I will be putting it on in the next week or so and then get a new dyno tune. ill let u know what gains i get, im expecting about 16 psi (total) and 30 or more rwhp gain. GT500-07 03-02-2008, 06:16 AM im running the nitto thanks, stock wheels? is your car lowered? sorry for all the questions, but I've been looking for a 305/40/18, no luck. I see the 305/45/18 are 28.78 overall dia and just want to make sure they will work for me. gt550 03-02-2008, 08:00 AM my car is not lower.no rub wait and get 305/45/18 m/t they work better GT500-07 03-02-2008, 08:47 AM my car is not lower.no rub wait and get 305/45/18 m/t they work better thanks Justin@VMP 03-03-2008, 12:03 PM Some have made claims, but I've yet to see any dynographs from 2.6 upper + 10% lower, complete with air temp data. It's hard to say how hot the stock blower will get when run that hard.
