After removing the cat(Yeah Yeah I know) I've considerably lost low end, and maybe 1 - 1.5 mpg where can i compensate in the tune to regain that power and the mpg ?
Thanks

I can understand, a little, the low end loss, but the decrease in economy is surprising. You might run thru the AutoVE tutorial a bit to see how far off your tune is and adjust accordingly.
Did you get past the previous problem (reduced power mode , and full flash) ?
If so how and what was it ?

From the Scan or Tune tool help menu click Help -> Tutorials -> AutoVE tutorial. The tutorial is specific to the Gen3 PCM's an may not apply directly to your TB. There are Gen4 specifics floating around the forum somewhere. I'll see if I can find it for you.
I never had a rep light, i just did'nt want to get one if i removed my tuned pcm and replaced it with a stock one, i am running an efan on the trailblazer, and i know that gm was kind enough to build a pcm that's pretty much useless for any kind of tuning as per what i am seing more and more, nothing comes easy on this one...lol
for the full flash, the competiton does it, but it also has its flaws

Here it is. It's a sticky in the Gen4 section.
I haven't done much outside the Gen3 PCM's, but I'm thinking you may have the option to utilize the virtual VE table for part of your tuning.
The reason for a full flash is that i am starting to doubt the reliability of efilive when it come to flashing just the cals, i've read a few posts and experienced myself now that some pcms might not take teh flashing on teh first shot, even if it says so, i've had my pcm flashed and i am strating to beleive something failed somewhere, as i still have some options that are not ticked...
with a full flash at least i could be sure that i do indeed have a working flash or not...works or does not...
