High end power

[TALONFACE]

My car has loads of low end power, but i cant seem to the high end up??? Once the turbo spools at 3200 and ends thats it. If i hold down the pedal boost drops off a little abit, which is normal, then theres not much power after that. But is there anything i can do to get more high end power, check my profile for any info!

First of all I have a dejon tool dual stage boost controller, and it set at stock boost which on my car is 10, and high boost is 15. My problem is when i switch between them, there is not much difference in power, but there should be a pretty noticable difference, and my boost gauge reads 10psi, and on high it reads 15psi???, and at high boost the turbo seems to flutter abit?. You can check my profile for any info on mods!!!! Can anyone help please?/???? Thanx

Sounds like your turbo is about to shit the bed or you have a leak somewhere. I would first do the IC tester and then look around the exhaust area. Anywhere there is a coupling or blt holding things together.

A 14b that is ported should not act like that. It is not going to be a torque monster with a mild setup. Also the stock 4G63T dies of at around 6.5k that is with almost any turbo. The remedy for highend power is a nice set of CAMS, a larger turbo, and some tuning.

Hey I had problems similar, I was simply getting to much fuel, Had a upgraded fuel pump and not enough air, ran stong till about 4500 rpms and then it felt like it just stoped. Just an idea.
