Default Wont go over 5K with boost

I just finished installing my turbo kit (about ------- time) but I cant go over 5Krpm that easy, it bogs and really just takes for ever to reach 6Krpm. I have 2(or less) degrees of retard. on the distributer. I think I need to mess around with cam gear, what do you guys thinkAlso I'm barely boosting 5 psi at 4Krpm and it stays still after 5Krpm
My setup
HF manifold, running a TDO4L, with 440cc DSM injectors, and Hondata. Thanx

could be a tuning problem, maybe too much fuel, but I know nothing, my car is broken.

Who tuned the Hondata? You or a dealer?

what kinda of air filter is on the turbo?

also, i'd say its either running too rich, or too lean.

you should take it to a dyno for some tuning.

My friend is a Hondata dealer; so you said its probably to rich, I'll hook up a wideband and check it out. But damn its feels good to be boosted (too bad its really not tuned). The whirl of the turbo is ------- loud!!!!!I'll get back with you guys w/ pics and might need more advice for tunning my car. Thanx I really appriciate all the info. I've learned and will continue to learn, I've never thought I get this far, but I finally did.
P.S. Merry Christmas to all HMT members

Hey man, i had the same problem with my car, it wouldnt go above 5K and i tried everything i could, it ended up being my timing, even though it would run fine n/a, but when under boost there was no hope in it getting over that, so if i was you, i would play around with the dist. and see if it helps or hurts any, and then go to the cam gear, good luck and Merry Christmas
