andrich Member 94 Member For: 15y 10m 2d Posted 09/06/12 11:03 PM Share Posted 09/06/12 11:03 PM Hey guysOver the last few days iv noticed my boost gauge going to 15-16psi but it's tuned to 12psi. It has been on cold nights but I was/ am still a little worried. Should I be worried?? Maybe the actuator not controlling the boost?

andrich Member 94 Member For: 15y 10m 2d Posted 10/06/12 11:06 PM Author Share Posted 10/06/12 11:06 PM thanks for the replies guysahh so it would seem its not to uncommon. but obviously better if it doesnt happen lolI did know that on a cold night it will push a few more PSI but it worried me when I saw 16 lol (however it was only on my boost gauge which may not be 100% accurate anyway lol)Im looking to do the actuator and posting/flapper with my nxt tune, along with plazmaman cooler and valvesprings so hopefully can control the boost properly. cheers guysmichael Link to comment Share on other sites More sharing options...
