Welcome to the forum vyper202! You can expect replies like this from time to time. This forum is full of knowledgeable people, but have answered the same question many times. Familiarize yourself with the sticky section and use that search bar. If you're a newbie to cars in general (not just the C4 or entire corvette platform) just keep in mind that there are tons of BS products designed specifically for ignorant consumers! Ignorant in the literal sense, no offense intended.
While having a "Dumb" moment I bought one a long time ago. It was supposed to advance the timing and other things to "improve" the performance of the Corvette!
Using a GTECH Pro I was able to make several runs with and without the device. It made no noticeable power difference, not even 1 hp better or anything. After testing with the Gtech it came off the car and has not been on since then. The Gtech is able to detect a difference of as little as 1 hp and it made no extra power anywhere and did nothing to help the acceleration of the Corvette.
I hate to admit to doing a stupid thing but buying into this item I got suckered! I do not have an air foil but I am using the smooth hose to transition from the MAF and the throttle body.... I should have just bought a decal!
