Ya why is the short trim different for each bank? Im not too well versed in tuning but they should be close to the same right?
I have some extra o2s lying around if you wanna try it out.

no, fuel trims are going to vary between banks.....I am friends with Steve (Frost) and watch him tune many cars (and try to understand)
if they are way different than that would indicate a problem but other than that, the trims should just bounce around close to zero (but don't forget this is a start up tune).
The procharged black camaro I just built had a start up tune on it and the trims were swinging from -30 to +30 and car still ran alright

During the hesitation, not much difference. Maybe swings -2 or so more on both banks. But if I try to hold rpms at 2000, and the surging starts, then the Bank 2 side swings all the way to -12.5 while the Bank 1 side stays at -3.0 or so. Make anything of that?

What is the tps voltage when u step on the gas? Does it read at all? Also do u have o2 extensions on the car ? if so they are garbage, not saying thats ur problem but I would get rid of them bosch 13111 o2 will work just fine. Disconect the pressure guage and put a manual one on there to see if the readings are the same. If there is little to no carbon build up I think its not getting enough fuel.

Well I'm not sure that is something to worry about...still doesn't seem like too much of a variance
What exactly did you change on the car since the last time it ran? Steve knows his stuff when it comes to procharger cars......he has a LOT of time in mine as well as MANY others.....so if he says it's not in the tune, then you can believe it.......I will do my best to help figure out whats wrong
Did you buy new 60lb injectors? are you sure they are the brand you believe them to be?

I did a search for the p0300 on here even though your not spitting out that code anymore. It seems like the causes where bad o2's, vacuum leak, plugged cat, or bad coil. I think we narrowed out the vacuum leak. If it was a coil then it would at least spit out another code? So only two left....

I bought new injectors off a forum member who regularly sells them in the classifieds. I was told they were Siemens Deka 60lb injectors. Let me check to see if there's a number on them I can cross-reference to be sure. And let me just tell you...if they aren't Siemens Deka 60lb injectors, I'm going to be super-f'n-pissed off.

I will pull the O2 sensors and the extensions and examine them, and clean the connectors and see what happens. I surely hate to throw money at this problem and just buy 2 new O2 sensors for nothing.
