Corvette Fast 90 owners beware...
You need to keep an eye on your MAP sensor and/or relocate it..
I had a problem last week at the track where i spiked lean in 4th @ 6k... After reviewing the data logs I noticed my map was falling as the motor would torque up and was happening every time I nailed the throttle. Anyways the old one was banging on the firewall hard enough to cut the fiberglass... I ground off the tabs on the new one and cut a small piece off the area it was hitting and cured the problem. I would have just relocated it but had the wrong fittings.... I have since looked at two friends cars that were both doing the same thing. One I data logged and showed the same map drops but not as severe as mine.

FAST recommends you trim the firewall for clearance of the intake. We had a car at the shop that broke the MAP sensor when the engine torqued during a hard shift, needless to say it didn't run right anymore. Clearanced it and the customer is very stoked about it now.
