E28 528e, E30 325e Turner Motorsport Conforti Performance Chip
528e, 325e (E28, E30) 1985-1987 The 2.7 liter inline-6 is a torquey car, however, performance drops off greatly after 4000 RPM. With a TMS Performance Chip power is boosted at all RPM but most importantly in the upper RPM. The car really feels more alive! This chip was tuned on the dyno to yield as much performance from this engine as possible and still maintain its strength and durability. Jim Conforti tuned the fuel and spark maps to take advantage of 91 octane gasoline. By making the engine more efficient with this fuel, gains in horsepower and torque are achieved as well as making the engine run smoother.
I doubt thats a net gain though, its probally across the whole powerband. Thats how alot of these companys get away with saying stuff like that. From what I understand... @_@ (ps. that was a disclaimer absolving me from all responsibility to put forth completely factual information. Eat it! )
Beware of the cheap chips. There are quite a few advertised that say they do a lot of the same advertised results- and all they really are is a resistor to make your car think it's colder outside. If its' an easy 2wire hookup, it goes to your A/T sensor- that's it. Colder air is denser, so your computer adds a few percentage points worth extra fuel. Read the book, make a few choices, try them out yourself. It works on my 528e, as well as my Goldwing and my wife's Taurus LX POS.There ain't no miracles.
