Adding a TMS Performance Chip gives you the biggest bang
for your buck! Jim Conforti tuned these chips on the dyno to boost mid range
torque and increase horsepower in the upper RPM range. Where the stock V8 seems
to fall flat above 5500 RPM, the adjusted fuel and spark maps deliver more
horsepower to keep the engine pulling all the way up to the new 7000 RPM rev
limit. The best thing is that there is NO downside to installing a TMS
Performance Chip. Turner Motorsport has been in the BMW chip business for close
to 10 years and all chips are dyno-tuned to achieve optimum performance and
safety. As an added feature, the top speed limiter is removed. Premium 91+
octane fuel is required.

before ordering. We need to know the ECU numbers, transmission type, and production date of your car so it is recommended that you call your order in at 800-280-6966.
With the CSi BMW really turned out one of their finest
engines. A touch more tuning by Bosch Motronic expert Jim Conforti yields just a
little more punch from the big V12. Conforti altered the fuel and ignition
mapping to take advantage of premium fuel (91+ octane). Although the 850CSi is
required to run "premium" anyway, it is not optimized for it. Changing
these settings results in more power and a smoother-running engine.
If you're looking for a significant bump in power you need
not look any further than a TMS Performance Chip. Designed to maximize the
advantage of premium fuel, Performance Chips safely alter the fuel and timing
maps which results in more power and a smoother engine. These chips were tuned
by Jim Conforti on the dyno with fantastic results. What you feel is more power
starting at 3500 RPM and continuing up to redline. There is no downside - only
an awakened engine and a car with new life!
For the 850i/Ci we need to know which computers were
installed on your car. Please check the ECU number located on the computer's

your car is a manual or automatic transmission.
