i had a s475 and i would see about 10psi, i switched to a smaller s465 and it saw about 10psi also. drove it for about 20 miles then i gave it about 60% throttle and it jumped to 14psi... should i put a smaller spring in the wastegate? i was talking to a guy that knows his turbo stuff locally and he said a boost controller wouldnt help my problem, he says my wastegate might be too small? the whole kit is from kbracing.

what you guys think i should do? i really dont want to buy another wastegate

 

Did it stay at 14psi or just jump there and return to 10?

 

well i turned the corner i got into i think second or third gear and gave it about 50-60% and i saw it go strait to 14psi so i let off. didnt want it to take off past that and blow my **** up.
