First Rado, bought a nice 2004 crew Z71 and had fun tinkering this weekend... I've read through many a sticky / thread here and completed a few maintenance recommendations. I can say I'm very pleased with the results...

So far besides an oil change I've:

- Removed the Airaid throttle body spacer that was on it
- Removed the Jet chip on the P12
- Cleaned the dirty ass throttle body
- Seafoamed the intake through the evap port
- Cleaned the MAF
- Replaced the MAP, as it was bad causing my idle to drop below command
- Verified leak down was good

After all that purring like a kitten but didn't stop there...

Broke out my HPT Pro and started tweaking.

So far here is what I got:

- Retrieved a base file for backup (saved)
- Bumped the trans shift pressures up
- Changed my idle curve
- Changed Stioch AFR to 14.2 for E10
- Removed some TQ Management
- Lowered LTFT min to 85f
- Lowered DFCO RPM
- Raised Piston Protection = 4500 rpm for better MPG
- Made following changes to COT for better MPG

COT adder MAX = .15
COT Temps (all four) + 200f


Overall a good weekend... Ill do some logging and make changes to the PE this week. Here is my HPT file for review & recommendations... I'm also looking into enabling my Lean Cruise mode as I'm in Alberta where cats aren't even required... LOL Which will be coming out later this spring...
