Speed Density Mods
Q: Do I need a new chip after every mod on my 90-92 car?
A: Absolutely not. The 7730 speed density computer can compensate for almost every mod. Only a cam and head swap might reduce the vacuum enough to need a new chip. You can put headers, cat-back, port the intake, etc, and the computer is still happy.
