Hey I was wondering if anybody else has gotten this problem too. Well when I press on the gas all the way, my 03 escalade hesitates to go and then when it does it runs real bad. At 80km/h she just keeps bouncing the rpm at about 5000rpm. It's almost like it wont let it into the next gear. Same as if I am doing about 80km/h and hammer on it it won't let the vehicle go past 100km/h and bounces between 4500-5000rpm no matter what unless I ease off the gas. I got a magnacharger but don't think it has anything to do with it.
Off the start when she hesitates to go she seems like a standart car ready to stall. Bouncing back and fourth.
Anybody got a clue what is wrong? Somebody told me it could be the fuel pressure regulator. But why wouldn't it let it to shift to the next gear?

With the limited info you give it could be many things, but I have about 8 customers with supercharges and every one have blown at least one trans, some as many as three. It could be a fuel delivery problem, or a trans problem, you need to find a good shop in your area.
