My last thread about the weird noise on start has come to this:
After setting Edge on stock level, my service dude cleared these codes and I have not had a noise yet. He says the noise was 'turbo bark' because the chip is interfering with the engine warm-up process..in other words, the edge did not wait for the 160* temp, it was working from the start. I will call Edge about this.,will be interesting! I am still on stock level and no problems.
On the way over to the dealership, on level 1 ,the boost would hit 13.4# and the engine would act like it was missing every few seconds until down to the high 12's would run ok again.

p1226,p1229,p1238,p1241,p1244,p2563

Thanks!

Those are injector control ckt codes

Carefully check the connection under hood where the juice plugs into the truck.. look for any backed out pins etc
