Exclamation WTF is up with my power?

Ok I have a 10th anniversary turbo II with a full exhaust, fuel pump, intake, fcd, and fuel controller.
This is my secound post im keeping this one and my shifter one seperate so I can get more feedback.
Ok today along with my wierd shifter I hang out with my friend and he has a civic, We do a few roll ons. The roll ones I shift fine I slowly creep by him but thats after the turbo is spooled and I have boost creep so I have to shift at 5k due to a full exhaust and a cone filter. His civic only has exhaust and intake I believe, but shouldnt I pull on him like its cake work? same with this kids eclipse I can beat him but slowly I pull away not quickly. My car would stutter at 5500rpm due to boost creep but I shifted at 5k. please post comments!!!

fix the boost creep. port that wastegate. when you are shifting at 5k you are boggint the motor down by taking it to a low rpm in the next gear.

its a 2.5" system to a racing beat system, walbro 255lph pump, apexi safcII, added 15% fuel from 4600-7600rpm. I'm now a tech at a local shop (im happy) he said we would work on my car tuesday. I know we are ripping off the turbo and porting it. I guess I should rip off my twin scroll, due the tb mod n rip off my emissions if we can get the turbo job done quick enough.

what about a manual/electronic boost controller would that help the overboosting problems ? or would you still need to port the wastegate too ?

maybe if you did both it would work out really well

Boost controllers can only RAISE boost, so that wouldn't do any good. Too control boost creep you need to port your wastegate.

A boost controller would restrict some flow to the wastegate, so that would increase boost. I just want to get rid of the boost creep so I can hit redline right now I can only hit 5000rpm then shift if not it stutters ands bucks. Since I will have my turbo off i'm also goin to port the inlet on the turbo to the gasket and take the twin scroll off. Hopefully doin all of this tuesday will give me a nice boost in hp since I can go to redline!

Uh...
This is why your car is running so slow...

Why are you randomly adding fuel???

That actually seems to be pretty common Ted, for some reason I've seen 6 cars personally that the people just decided to add anywhere from 15-25% from 4k to redline, and wonder why they run so poorly. When asked about it, they either comment that they tuned using their autometer a/f gauge, or they just added a ton for safety.

Ok, so your car is now safe.
Please don't complain that you can't whoop Hondas since you are running it safe.
