I'm running a billet 476/87 now on stock fueling. I love it. Drive it to work everyday. I just switched from a billet 475/83. That turbo was a laggy turd compared to the 76. But I think it depends in the driver and tuning.
Are you running the 1058 with your set up? I ran a 75 with the 58 and hated it but the 75 was also 75 83 1.0. Been looking at the 468 87 90 dunno how well the 1058 will do tho
Going to go with a s468/87/90. Anybody got one they wanna sell just asking be for I order one this week lmk if you do
