GT700 Sputtering at high rpms (Part 2)

Original Thread: https://www.6speedonline.com/forums/...d.php?t=135238

So I changed the sparkplugs and put in good fuel. The car is still sputtering at high rpms in the upper gears. No check engine light, and the car drives fine, just when I step on it, it starts going crazy.

I checked all the hoses, everything is good. What can it be??

Did this problem develop after you removed the cats?
