This Tbi Adjustable Regulator is needed for stock and modified GM tbi engines. At 3/4 to WOT the computer uses a fixed program for max power. Therefore,since it is not reading the A/F ratio you may need more or less fuel for maximum power. This regulator let's you change what the computer can't.

Includes installation gaskets and instructions.


Note: We highly recommend the use of our fuel psi adapter and guage to accurately read fuel pressure.
