Feedback from people that have installed the streetmaxr 65.5 turbo and 37" tires.
I am looking for feedback from people that have installed the streetmaxr 65.5 turbo and are running 37' tires on their truck. When driving around 50 to 55mph area does your truck shift into 6th gear? If so does the rpms stay high enough when you give the truck very light throttle to accelerate when going down the road that the turbo builds boost and exhaust manifold doesn't climb high enough causing compressor surge? The reason I am asking this is my truck will stay in 5th gear until around the 65mph area with the tune I am running again for this turbo because of the turbo making the noise in the tune that shifted earlier. The tune I tried that shifted earlier because I didn't like how long the truck would stay in 5th gear before shifting would shift into 6th gear around 50 to 55mph. Then if I tried giving a little more throttle the rpms would be too low and the exhaust manifold pressure would go high but barely build boost causing the turbo to start making a noise like it is in compressor surge. I was told that with the streetmaxr you don't really want to see under 1450rpms for this turbo when cruising and trying to build boost. So after finding this out about the streetmaxr I am definitely going to be looking into regearing my truck because I have the 3.55 gears with the 37" tires to get my rpms up to around stock or a little higher than stock in 6th gear. Has any one regeared their truck running 37" tires and the streetmaxr? What gear setup did you go with? Thank you for taking the time and reading my post.
