Hesitation at WOT?

[SweetRide]

Has anyone else had this issue? Any help would be appreciated as I'm hoping to head to the track tomorrow.

I'm running 8r18 on my Predator, with 93CAI canned tune & raised shift points and raised rev limit.

During my WOT run today I noticed a cycling hesitation at WOT right before the shift(s). It wasn't massive and didn't trigger limp mode or anything... but was definitely there. Almost like it wasn't getting enough fuel rather that hitting the rev limiter. I will raise the limit to 6750 tomorrow and see if it happens again so I can rule that out. (Stock values for this on my Predator are 6600, and I'm currently at 6700).

Please let me know if this is common, and if there's a fix so that I can run times with confidence this weekend.

Thanks in advance!!!
