Don't get it. Why is boost creep so horrible? It seems to happen when you punch it in 5th or 6th at lower RPMs, the boost builds up, the cylinders are drawing in some air but because the RPMs are low, the cylinders don't draw air faster than boost builds = boost creep. So more boost = more hp. Not so bad. Ok, you go over 17.5 or so PSI and then you get fuel cut. Don't think you get fuel cut. That's dangerous, it's probably ignition cut. Big deal. I bounce off the rev limiter all the time when I autox.
I've punched it plenty of times with a TBE installed in 5th or 6th for quick passing but I'm never on it for a long time. If I really want to get going, I drop it into 3rd or 4th. Never got ignition cut. Even if I did, that wouldn't bother me. What I see as a problem is installing an FCD and getting 20+psi. Even then how bad is that. No one has tested to see how durable our engines are.
So why is boost creep so bad?
