i have a k04 and boosting at 20psi dropping to 10 is that normal??? also the car cuts fuel or shutter when puch at 30 mph??? please help???
thanks!

 

need more info. Is the boost hitting 20 then falling to 10 right away or somewhat gradually after 5k?

 

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!!!!
