I have a 20g and it flutters at wot. My cure the the problem is put back my stock intake system. Also adjust boost contorler to a psi level that will have less surg. Driving with surg slows you down and wears out the bov and turbo.

 

Yeah... I Should be running at 21psi per AMS, but I think I'm spiking a bit high... I'll have to take a couple passes and adjust it... but right now it's 10 degress outside... Probably a bad time for a realistic "Tune", hahaha.

 

lockportevo8, i got the same thing happening to me, I was just describing the bov flutter in my last post.

 

Ah, I See, My bad, lol.

 

tomorrow im gonna take the evo out since the snow is melting some and we are suppose to hit mid 40's this week and i'll have a chance to look at the problem and do a little tinkering to see of this problem will persist or not.
