Default Stalling after cam install

Hey guys I am just looking for a little advice here. I just put in a cc503 cam, 1.6 rr, long tube headers, cat delete, egr/air delete. And the car seems to idle just fine. However, when I go WOT and back off the car will stall out. Could the stock injectors and stock tune be causing my problems? BTW it is a 93 corvette LT1.

stock tune is likely your problem.

stock injectors shouldn't be a problem, atleast not with 24# ones not sure on the 22# injectors

Sounds like an easy fix. If you have TunerCat I would adjust the Throttle follower IAC offset vs MPH.

I am not sure what that means. Should I just buy a tune from PCMforLess to fix the problem?

You for sure need a tune... you think your factory tune is working for that setup? Contact LT1PCMTUNING or PCMFORLESS ect ect they'll get you hooked up.
