hole in acceleration

[raevan79]

My 07 grand prix with the NA 3800 will jump off the line pretty good, but at WOT there is a lack of power from 3100 to 3400 rpm, then it takes off again. Thoughts?

[BillBoost37]

Probably an area in the tune where if it downshifted or had the right afr it would be much better.

Perhaps it's something else bill.


Does it stutter/jutter and then take off?

Feel like a misfire or something?

Bill: From a dead stop, it will do it in 1st, then again in 2nd, all gears.
five finger: no shutter, does not feel like a misfire.
