I tried all that already.

Techstream shows the same calibration ID no matter what you do with the Bully Dog. Once you flash it you're done. No going back. At least not with Techstream.

 

Turns out one of the hoses to the fuel pump was partially blown off and was barely hanging on and was causing fuel delivery issues. They're gonna out everything back together and test it and we'll see what happens from there

 

Good shit. What's the ETA on that?

 

They're already finished. I told them to check my drive shaft while they're at it because it's been vibrating and squeaking real bad and when he looked at it one of the arms of the ujoint housing was eaten off. So now I've got to try to find another one of those used locally without ordering the whole damn drive shaft.

Sorry if my parts terminology is off... lol.

 

Search for a driveline shop... you never know.

 

Yea that's what they did. They're over there now getting it taken care of.

 

Wow night and day difference. Works like a beast now.

 

Congrats man

 

Thanks man. I appreciate your help.

 

Damn I'm hittin 9.5 at WOT now. Never saw below 11

 

Glad you got it taken care of. 9.5 is pretty rich but it's better to run rich than lean. ​

 

Finally took the truck out for its first drive tonight. Had it idling for a while in the driveway a couple times. Running 8psi and 11.5 afr at wot. Pulls nice. I have 2.85 pulley, Walboro 255, Doug thorley long tubes, 76mm throttle body, airaid Intake.
What does every one think?

 

So you have the long tubes, what is the rest of your exhaust setup? I've been thinking I'll eventually do headers and exhaust on mine.
