Critique my tune / adding more boost (LLY)...
I have a 2005 CCSB 2500 6.6 LLY and 5 speed Allison trans. It's pretty stock except for a AFE turbo mouthpiece, pcv reroute and a 4 inch catback (stock downpipe).
I have tuned it using some of the repository tunes but I'm looking to clean it up some. It is a little laggy and does smoke a bit excessively (quick throttle change, downshifting to pass, WOT seems decent.. just a little haze). I'd also like to increase boost a few lbs, though i don't know if i am doing it right or not. I added some in the desired boost tables and just get underboost codes..
So here it is, any and all opinions are appreciated!
