Obsessed
Just wondering what other's results are. I still haven't got a retune so I'm running a gl4 designed for the gm-4. I was coming back from town last night and gave her a slow roll in to 85-90mph and the boost creeped over 22 psi. So I tried to recreate it with the camera out and the boost actually jumped when shifting to 25 psi and held 22 steady. I was just wondering if anyone had got this much boost out of one of these. It won't let me post the video through tapatalk app so I'm gonna post to YouTube then post the link for you guys.
