Cool Air Temp Mod The latest in our series for you do it yourselfers. This is mainly for those in a warm climate. This will make your air temperature gauge inside the AFM (ST165/ST185) always read 68 degrees F. During the summer if you let your car idle or sit at a red light the Air Flow Meter will heat soak and the temperatures read by the sensor are extremely high. This causes the computer to retard timing and hinder your performance. Even once moving and colder air hits the sensor, it takes time for it to read normally again. This way it reads a colder signal all time time.

Adjustable
Fuel Cut Mod Originally created for an MR2 3sgte, will work just
as well for All Trac. An adjustable fuel cut will still allow you to
run all the boost you like, but still have a fuel cut at some point
just incase something goes terribly wrong. This could save your
engine!

This will raise your fuel pressure without a fuel pressure regulator, give u a little more acceleration off the line, and give you almost 2 more
psi. All you need is a 5-6 feet of high quality vacuum hose. The link above will give you a poorly drawn diagram. But enough to give you the idea.
