No...I punch it, she'll start to gradually boost but the second I get to 2500 rpm's, which happens pretty fast (what stall is set at) it goes ape shit & boost gauge reads a little past 21lbs....I get off the gas & she wants to cut out.
Just tuned my GN, and once I hit 2500 rpm's, I go from 0 boost to 20 and I'm all over the road. Thought the issue might be a boost controller valve which I purchased & put in which would be able to slow down & gradually boost the turbo....no dice. Thoughts?
