depends on the version of the cobb tune you used… you could have had an issue with the WGDC (waste gate duty cycle) in the map and not able to hold boost or it may have been holding it too long… i dont know… i didnt datalog the car. either way, im glad justins tune get the car straightened out enough for it to perform SEMI normal. still a 92mph trap is weksos. launch the fuckin pants off that thing, and beat it like it was a downtown albany hooker who wont put out. i guarantee with a good launch alone you will pick up 3-4mph in trap… then nail ur shifts… GUARANTEED 1375 or better if i whipped it a few times… (warning, not responsible for broken, cracked or shattered parts)
