Perfect - Thank You as well. I will take a gander!!

Awesome - Thank You for all the suggestions!!!!

Lol so true

2012 Chevy Tahoe 5.3 flex fuel - any tips for better smiles per gallon ?

Oh okay sounds good.

I think the cam is good up to 6800ish rpm

Oh okay - had been thinking the oil pressure seems a little low for my liking and what is the rev limiter set at ?

I couldn't be happier - it fires right up, idles great and I can lower the idle if needed. You are awesome and I can't thank you enough for your time and patience !!!!!

Will get the speedometer...

got sidetracked - here is current log

Updated log - Thank You !!!

2 logs

Okay going to install 12.hpt and get a log.

pm sent

I am good with going MAF/SD for now. Long term I think SD for the win.

Do you want me to go ahead and install 11.hpt for now ?

Updated log

Gm - everything seems to be great - I will work on the speedo this coming week - after this tune is installed and logged let’s leave it there until it’s fixed - it’s still running in VE only no Maf ?...

Good day all - updated log

Gm and Thank You !!

I am working on the speedo thing - I believe it’s a wiring issue.

2 logs from cruising today

Will let it cool off and get another cold start this afternoon.

Have a great day !!!!!!!!!!

GM everyone - I installed tune attached - fired it up - let it warm up and then opened the throttle blade to bring iac counts down on first log.

2nd log I reset tps as well.

Thank...

In the morning I will open the throttle blade until it will start on its own - let it get to operating temp - get IAC counts lowered so on cold startup it has has much room to open as possible and...

I have and can again

Well is there any hope here ?
I appreciate everyone’s help and suggestions. This has been one heck of a headache for me as well as you all.

Thanks again !!!!!

used the pedal to get it going
