| I make 520rwhp on 94 octane with these. Boost and response is at least as good as stock. 6psi by 3000rpm and 24psi by 5000rpm makes for a really fun car to drive. Im happy they delivered what they were hyped to deliver. As for wastegate problems, my boost always held nice and steady, no problems there. Ive got some dynos with boost pressure at home somewhere. I also had stronger springs installed by specialty Z when I bought them. Cause there are so many dramas surrounding these though, I am currently getting rid of the internal gates and fitting tial external gates. Then Im going to boost 30psi and see what the max really is. Note for the panic freaks, this is a tuned 30psi not just randomly cranking up the boost along with some aquamist.
