Hesitation at WOT now?
I have been having this quick hesitation problem with my EVO ever since I got the car. What it does is when I hit the gas, the car will accelerate properly and get to a certain rpm and then it will cut back and then give me full acceleration again to redline. It only does this once. It's like a small hiccup. I thought a reflash would take care of it but it didn't. It only does it when it's real hot outside too. This led me to believe the car is just running a tad on the rich side (at night it doesn't do it).
I just got the TBE yesterday and it is more prone to do it now. I'm getting the car custom dyno tuned on Shiv's dyno on Friday.
I just wanted to know what you guys think it may be other than needing a tune.

Why could it not be that the car is too rich at a certain rpm/load?

Remember, it's a hiccup. Nothing more.

It would be more prone to spike in very cold weather, than in hot weather like he said. Does it throw any cel's? Boost cut is alot more than a little hiccup, feels like ur hitting a brick wall. Let shiv take a look at it on friday.
