I am having a problem at Wide open Throttle (WOT). My Typhoon is not able to red-line (under load) at WOT. I have to bleed my foot off the gas and then it just shifts into gear. I have better power at 3 quarter throttle or 75% TPS. I changed the plugs, compression test, run good gas. My max boost is lower than stock. I am running around 11 psi but I should have 14.7. I not getting any knock. It just won't power up to the red line.

clogged cats?

That's funny you say that. I was thinking that was one place to start. How do I check for that? Could it be an injector or a Fuel Pump? Maybe the stock air fuel pressure regulator is bad?

yank the cats off, and straight pipe where the cat used to be. They don't check for that in this state, it's illegal but I've never heard of anyone getting checked since we have 0 emmissions or inspections. you didn't hear that from me :D

Turbo motors like a free breathing exhaust anyhow.

I got a bad cat. I got white coral like sustance in little chunks. I shook it all out into a pile on the floor. I ordered a new cat from summit for $125. Back order 3-5 weeks. Thanks YaLL

P.S. I have to have a cat because of my Turbo.

We run without a cat in ours...but you just have to beware of turbo spiking. Took a hammer and sickle to the cat several years ago.
