Issues with tune/ waste gate

[Mario U]

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?

So you can drop the hammer and the car will not start to build boost until 2500 rpm?

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.

Sounds like there's nothing wrong....except needing some stickier tires!!!

Many people would pay for those type of symptoms.

I was thinking the same thing, LOL... Sounds like a pretty great problem to have, so long as there's no KR.

Your combo might be a little off. I can't see signatures on the mobile app.

Light convertet, big turbo?

If that's your car in your avatar, I'm going to say it's your tires that are the problem.

That's what i was just thinking and getting ready to post the same comment about those tires/wheels.
What are those 24's?

List all your mods to the engine/car that may help.

I didn't see that....the wheels.
