Here are some more information for Mod Chip Bmw:
The VW and Audi TDi diesel vehicles are probably the most economical cars on the road, getting about the same or better economy than the new hybrids. They are the best way to go when looking to save money on fuel. The VW TDi's especially are growing in popularity in the U.S.. There are some complaints though. Like not having the power needed to pass someone on the road. This has all changed in recent years. There are several upgrades that can be made to the TDi's to improve power, and to actually improve fuel economy even more. I will touch on these subjects briefly.
The first TDi Performance mod that comes to mind is an upgraded chip or tuning box. Both of these items, the VW performance chip and the VW tuning box change how the fuel is delivered to the engine. For a VW performance chip to be installed, the TDi's computer must be removed and sent to someone who can solder in the new chip with the new program. A VW tuning box will simply be connected under the hood where it can intercept the signals going to the engines ecu and alter them. Most people will say that the upgraded chip will do the most for you, but the tuning box is the more common upgrade just because it is so much easier to work with. Also the tuning boxes are well liked because they can be removed and have no trace of ever being there so that warranty work can be done.
The TDi Performance upgrade that comes to most peoples minds first is the cold air intake. An upgraded cold air intake in a VW TDi will add approximately and additional 5-10% increase in power and economy. It is able to accomplish this by 1) Flowing more air which helps the fuel to combust more completely, and 2) Cold air intakes are sealed away from the hot engine air. Cold air takes up less space, so in turn more air is able to occupy the same area because it is cold and not hot. That is a pretty good jump and the cost for the upgraded air intake is minimal. One of the drawbacks is that upgraded air intakes are not available for all of the TDi models or year groups. There are also performance drop-in filters for most of the TDi's that will increase airflow slightly, and add a little power and economy.
The next thing that comes to peoples minds is an upgraded exhaust system for their TDi. The only problem with that is the lack of mods for the TDi exhaust. There are currently no major companies that manufacture full TDi exhaust systems to my knowledge. A custom system can be made, but often cost in excess of $750. So most people do either 1) A mufflerectomy where the muffler and resonator are removed and straight pipes are put in their place to reduce restrictions on exhaust air flow. This doesn't really give a measurable power or economy increase, but does give a throatier sound that some are looking for and the reduced back pressure will add to engine longevity. Or 2) People will replace the muffler with a new muffler that is able to vacuum the exhaust out the tail pipe. These mufflers will add a little performance and economy, although still not very noticeable, but they will greatly reduce back pressure to add to the longevity of the engine and will also add a deeper tone that some are looking for.
Another common upgrade for the VW TDi is upgraded injector nozzles. Upgraded injectors or injector nozzles and an improved spray pattern than the stock injectors and when required are able to flow more fuel. They greatly add to performance and add a little economy too. They are also an inexpensive upgrade, and high on the bang for your buck scale.
There are also other things such as propane injection or water methanol injection that will add power and economy but I won't go into detail as they are not common mods for the TDi's. Also with any modifications, a set of gauges should be added to monitor the VW TDi's engine parameters and to make sure that things are functioning properly.

What is Car Remapping and What Can it Do?
All you need to know about car remapping and the services that can be done to remap a car's engine. If you want know whats done with your engine before you have it remapped please read on through this article and you will have a good knowledge on car remapping. Have you wanted to know more about whats done when a car engine is remapped? Do you want your car engine remapping but not sure what you getting into? This article should give you a better understanding of what car remapping is and what done to your cars engine whilst its under the remap.
ECU Remapping:
Ok lets start of with ECU remapping which is the software program that's in control of the "Engine Management System", also known as the "Engine Control Unit" (ECU).
The main reason people go for ECU remapping in their car is because all car manufacturers set a default value to all that's set within the ECU, due to some countries having to have lower settings because of laws and the different climate, weather and a number of other factors. This means that no ECU is set to its max performance for a single country, meaning that its only optimized for a mixed environment. This stops your car from performing at its best levels, the best way to change this and get your car running at its best for our climate is with ECU remapping.
You should preform ECU remapping on your car if you have made modifications such as exhaust, intake mods and engine parts. These "bolt on" modifications such as exhausts will alter the way a car engine flows and a change in air flow to your vehicles fuel ratio will often be caused by this type of modification. You could be losing performance through your fuel tables if you do not have your car remapped after such changes and modifications.
The most common ways in which ECU modifications are performed is by ECU remapping which is when a specialist tuner will use a OBD flash tool to make edits to your vehicles ECU to give it better performance or a replacement of the ECU may be done, this is when your current ECU is replaced with a whole new ECU in its place.
OBD Remapping:
OBD or On Board Diagnostics is the terminology meaning a cars (or any motor vehicles) self diagnostics and reporting capabilities of the vehicles engine. On board diagnostics allows you to access the information about your vehicles state and various other sub systems to allow them to be checked and edited if needed. As OBD has grown and changed through the years we have seen some major changes is the on board diagnostics systems, making what can be done with OBD much better and with more in-depth diagnostic capabilities, since it was first introduced early in the 1980's.
Chip Tuning:
Is all about editing a vehicles controls and how it handles, this is done with the editing of the EPROM which if done correctly will give you much better performance in many ways including more power, lower emissions, cheaper fuel and many more engine improvements.
As times have changed so has the possibilities of chip tuning and car remapping, by this we mean the ways that remapping and chip tuning have improved giving us more power with this type of car mod due to the many things that can now be edited and changed in this way. Since the early 1990's remapping and chip tuning have become more and more modern along with all electrical products, opening up more and more ways in which we can edit and improve the cars performance such as; ABS, valve timing, electronic throttle control, automatic transmission, boost control (turbo charged engines), electronic stability control, speed governor and many more factors of a vehicles engine.

Help my BMW with performance?
I am currently driving a 2005 bmw 645ci. I love the look of the car as I have blacked out my tail lights and windows, along with adding black rims. However I now want to increase my performance. Lately I have been posting questions about mufflers and performance chips, however I just need answers on performance. My engine is very sophisticated and hard to work on but I need more performance. Don't tell me to sell it and by a 99 M3 and mod that, I need specific Mods and websites to find them. I have about 4000$ I can spend right now that Ive earned as im only 16 and the car was a present from my dad. Are there superchargers for the 6 series? should I add an exhaust system? At this point im new to modifying cars but would really like to learn, all help is greatly appreciated!
OK for a 645 you should goto Dinan. They have exhaust chips and intakes for that series (i have an e90 2007) they also work with BMW and their part will not void any warranties.

its the best, a little pricey, but you should have known that when you got a BMW.
