Boost Creep possibly

Could be due to your filter, cold winter air, too much boost....

 

I really think its the boost solenoid reliving access presure.

 

dude its nothing to worry about its the soelnoid, i had a apexi avr-r and it did that all the time its the sound of the solenoid activatind cus its achually a WELL built one not the chepey that you got with your stock evo.....

 

As long as you dont have knock, Or any of the evil signs of blowing up your motor run. The only boost gauge i trust is a map sensor. all these funky gauges that you find are worthless to me, just Xmas tree lights, that and A/F gauges

 

lol, I had to laught at this one

 

I have a GM solenoid on my car, its the sound of the solenoid allowing some boost to vent to maintain the pressure your target, its nothing to really worry about.. Its wise to run your boost no higher than 22psi on pump anyway..

If your concerned, you could run a compression test to be sure you didn't lose a head gasket, but I honestly wouldn't worry it sounds exactly like what my solenoid sounds like.

 

did you ever find out what it was, my friend is having the same problem

 

Turns out that is was the Turbo XS boost controler doing its normal thing. swaped for a manual for simplicity. Any one want to buy a Dtec with game boy, let me know

 

Sorry, no more **** **** ****.... gigity gigity.... alllllllright... wait a minute, its not allright.

 

I don't know about you guys, but I'm boosting over 25psi (1.7bars) and no pinning noises what so ever. no detonations, Daily driver with 38k plus miles.

 

my srt-4 use to do that when the turbo would lag?
