chrleb2, I'm sure there are many here that would like to help, but if you're not going to provide the information people need, they can't do too much. Post your tune file and logs so we can see what is going on.

What was it...?

[chrleb2]

in the main spark table there is a cranking spark,gave it a extra 10 degrees for a total of 20 and took off the flare control,starts PERFECT.

Just working on one last little issue,has some low speed tip in issues but cant find a tip in table at all,im telling you chevy went out of there way to ruin a good thing with this fucking computer.The early ls stuff works so good and is so easy,this system seems to be not so tuner friendly.But im getting it.

I'm not surprised... GM's wrist doesn't know what it's hand is doing.

That is one of the best processors out there for engine management. Once you get it figured out you'll be surprised how good it is. We have several 900+ RWHP monsters that the E38 processor handles very well. Also many "big" cammed LS7s with big injectors and they run with stock mannerisms.
