Hey I was wondering if anybody else has gotten this problem too. Well when I press on the gas all the way, my 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?

 

it will do this if it's hot

 

sounds like the tranny could be going maybe...

 

I'm willing to bet your problems are in the tune... given your location your best bet would be to bring your truck to Wester's Garage (do a Google search) or another performance oriented shop to take a look. Being that you don't really know what you have or if it was installed properly you need someone to take a look at it and run a scan to see what it's doing. but honestly it sounds like it needs some tuning, the shop could also check your fuel pressure and run a wideband to get things dialed in... it's not cheap but it's worth it to get everything right before you break something

 

im with him...sounds like a tune issue...
