Corvette Tuning, Custom PCM Programming, Dyno Testing The point at which a custom
chip becomes a requirement is when you start to modify the engine, or swap a
different engine or transmission into a vehicle that never came configured that
way from the factory. For example: upgrading the exhaust, induction,
and/or cam will increase air flow which most computers cannot recognize.
Systems utilizing a Mass Air Flow sensor might be able to register this
increased air flow, but in most cases they will only be able to increase fuel
delivery and not alter the spark advance because of limitations in the stock
programming. Custom tuning can be tailored to your specific needs which
will take full advantage of the modifications you have performed to your
engine. Also, if you have removed certain emissions control devices for
off-road use such as the EGR valve, the EGR functions in the computer must be
disabled at the same time or permanent engine damage could result. If you
have swapped in an engine from a different or newer car, it's EFI computer might
require custom programming to run and perform correctly in the different
car. Custom tuning is a tricky business; no two cars are alike and every
different vehicle requires a specific calibration to operate correctly.
Sometimes a "perfect tune" may not be attainable on the first try, but we are
willing to work with you until you are satisfied.
