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...

Welcome from Stony Plain!


Have a look at Canada355.ca also. We have monthly meets in Red Deer; the 16th this month.
(I don't think I'll be able to make it this month though)
