Thanks Chris and yes on low boost its tuned on 93 and on high boost I used c16 but like you said I may need to upgrade the turbo to something larger its a little precision sc34 rated at 400hp the car on 93 made 370whp at 15psi and 415whp at 20 psi with c16. I love the quick spool and do not want to have a super big turbo that will have a lot of turbo lag like a 6765 Im more looking for a 5757,5765,or 5858 my goal is to make 500whp just for track based fun however the car already the car blows the tires off the car my best time at the track 13.4 at 121mph it suck there no traction
