By mechanical issue, I meant an exhaust leak, intake leak, pressure venting issue,...etc., something more related to tuning. As for my offer to help................your welcome.

It sounds like a tip-in hesitation issue. Does anyone have some standard ideas for fixing this? I have a similar issue on mine - I was going to try more throttle cracker air flow.

I would like to thank all members that sent offers like ls1-450 to help me. Car still has a hesitation like white hawk but had another person I met at the track staurday helped me today, back at the track. I pulled an all nighter switching the carb setup back to the injection he got the car to run alot better went 10.78 best today with the injection was running 10.40's with the carb so its working good now timing to get that hesitation fixed and final tuning done.

Have you tried using a different MAF? A bad MAF will cause the issues that you describe. Find someone with a stock MAF that you know works, put that on and take it for a drive. Just a thought.

Have you checked the PCm It self to make sure it is still running properly? It is possible that at some point in all those tunes someone screwed something up. Get a New PCM flashed with your Vin and start from scratch new a new tune. for all we know that pcm can be toast.

I dint feel the car is not ready it has been 9.30's last season on s SD tune so I dont see the big deal with closed loop being added ? all i changed from last season is the camshaft springs and went to closed loop. I am not tottally stupid I have been low eight in a door car I had with a 632 in it i built the complete car myself as well as 5 other cars, also this runs great with my friends carb setup on it with the MSD 6010 box everyshop around here is not reputable by any means the only shop i would consider well known is New Era they are a sponsor so I tried them last and the tune was worse than the tune I had before from TTP the TTP tune the car ran great just a couple hiccups now and then.
I'd be glad to take a peek at it for you...

Has your tuner tried this...
This will cause IMMEDIATE system check readiness.

Set to "NOT REPORTED" Concerning the MIL (DTC's) light codes...just turn them off "DISABLED"
