I recently bought a ppe xcelerator economy for my mostly stock lly. The only real mods are a deleted egr with finger stick. Stock trans, head gaskets were done, with arp studs, but no real performance parts.

I have torque pro, so I can watch MAF, egr, boost, etc.....

anyway, I installed the 90hp ppe tune, and the truck runs ok, not throwing any codes, BUT... I'm only getting like 10mpg its basically like the turbo has been shut down.... cruising around, it builds zero boost, never hear the turbo spool up at all, up a steep hill can hear the turbo a little but it nevers builds more than 6lbs of boost.

Does this have to do with the egr delete, and new rules for tuners? or is there something wrong with my turbo? or something else altogether?

Ideas, comments, suggestions appreciated. I was really excited to get the ppe. It would suck to have to go back to stock.
