timing issues?

[kid_mustango02]

I just installed the predator tune and advanced the timing. Since then my car runs like total crap when I first start her up. Doesnt matter if its cold or hot outside. It has alot of hesitation when I try to take off in the lower rpm's. It's to the point where I have to rev it up to over 2500 rpm's to get going from a dead stop or it will spit and sputter. Could I have the timing advanced too far? Would that cause hesitation? Help me out please.....

When you first start up your car, in the morning. The engine is not at 100% operating Temperature. You MUST not beat on the car right after you started it up after its been sitting. This will hurt the engine! Just drive NORMAL for a couple minutes..and then you can hit it. And It will respond better.

Just an idea but, I've read that with advanced timing you need to run premium fuel. Did you fill up with premium first?
