Thread: 1990 grand prix mclaren. top gun chip? tune download?

Jeff M used to make the Top Gun chips, but he disappeared from the internet a few years back. He had at least 2 kinds (Top Gun 180 & 160). Because the chip for these cars were rushed by GM, they had some runability issues from the factory. The most basic of Jeff M's chips took care of those issues. Each of the Top Gun chips required a thermostat of the same temperature as the numbers in the name of the chips indicate, as the chip kicked the fans on at those temps. There were some mild table changes, and everyone thought these chips were the greatest thing since sliced bread in the late '90s/early '00s, but nowadays, it's considered very mild/tame versus something like TGPilot's (Kenny) "Hot Tune" chip, which is far more aggressive. If Kenny's still around and selling those on the tgpforums, you might want to hit him up.

You need to have an eeprom installed, with CUSTOM calibration data ( tune ). There is only a handful of guy's I personally know that would be willing to do this for someone. A great guy to message is Adam Perkins. Great guy, does great tunes. Shoot me a PM and ill send ya his email.
