it tampers down to 10 or 12 psi. but in 2nd and 3rd gears at full throttle it sometime tamper to only 15-17??? no clue. is that to high boost for a k04-15? cause seems that my fuel or car is cutting out when going up hill the boost raise quickly then the car studders or stall??? in 75 degree temp the car runs pretty good with that adjustment, but now that is 20deg below i don't know if i have to lower the boost cause of climate change. please help thanks!!!!
