I have hesitation at around 4000 rpms, I don't have my boost gauge hooked up yet (waiting on my pod in the mail) But I figure I'm running around 6.5 psi on my drag kit (my tial wastegate is a .45 bar and turbo xs boost controller is set all the way at 0) I am pretty sure I'm just runnig really rich around my hesitating rpms, but I just want to be sure. I am sure that if I turn the boost up to around 8 psi I'll be fine, but I don't want to adjust anything until I hook up my gauges.

 

That was happening to me too. . . but I was running lean.

 

happened to me.
I was rich.

you need a dyno and wide band to tune it at those ranges. No other way. trial and error wont get you there.

 

I doubt I am running lean, my timing is also retarded 3 degrees.
