07 gt500 hesitation after new mods

[RARESNAKE]

I just changed a few more mods on my car it's an 07 with low miles

Mods added
15% innovators west balancer
Dual 65 mm Ford racing throttle body
Thumper tensioner
Sct x4 tune from Jlt performance


Mods that I already had
McLeod RXT clutch
No cats
Stinger exhaust
Jlt 123 mm intake
2.5 metco pulley

So here is the complication. The hard has a sputter feel when driving in low rpm and and under light accelerating. If you get on it, it feels like it's being held back. But it still screams I know it's not running right. Any ideas what it could point to? Throttle body? Tune? Any help would be appreciated.

It's probably an anomoly in the tune. I had a similar issue a while back.....contacted my tuner and it was gone with a revised file. It is likely related to your upgraded throttle body.

On another note, be careful. You're running a lot of boost and really spinning the stock s/c without any cooling mods. You need a heat exchanger and I would run torco if I were you.

I've heard a lot of guys dealing with throttle body problems on here is there a specific one that is less problematic? Or what I have is fine?

More than likely it's the tune, the FRPP twin 65mm is a very easy TB to tune.
