The 318i/is needs more torque - pure and simple. A little extra grunt in the bottom-end of the RPM range will get your 318 moving quicker in traffic. The torque gain for this engine starts at only 2500 RPM! If you're looking for a significant bump in power you need not look any further than a TMS Performance Chip. Jim Conforti tuned this chip to take advantage of 91+ octane gas. By altering the fuel and spark curves greater horsepower and torque can be achieved as well as making the engine run smoother and better responsive. There is no downside - only an awakened engine and a car with new life!

For a 1992-95 318i/is/iC/Ti, we need to know the production date, ECU number, and if the car is manual or automatic.
