Glad it worked out for you, i know how annoying it is when the a vehicle dies on you all the time... I learned alot when i went threw the same problems on mine after the cam and converter install...

Scott what you need to do now is get to the track and see what the new combo will do! It should do alot better now that it idles on its own and you wont be heat soaked soo bad.

 

as long as it beats a 13.4 I'll be happy

 

so you really didn't have an air leak...just bad tune. Glad you got it fixes

 

No he had a air leak, then he got a retune that had the air leak in the logs.. Basically all i did was adjust a few things, nothing major...

 

As far as I know, yes. But nobody said tuning this thing was gonna be easy, and it really took actually being there with the truck trying different adjustments in the tune. Also looks like I might need to get some new O2 sensors as 1 of them is getting lazy.

But so far it looks like everything is fine. I will be logging it some this week to make 100% sure that the problem was in the tune, and not an air leak somewhere. I did have a leaking FPR vacuum line, which was what was causing me hell down at Ennis on the 1st, but that got fixed right away. All it took was getting the fuel trims in line at idle and adjusting the start up to give the motor time to catch idle.

 

Hey Corey, would you mind sending me a copy of my current tune when you get the chance? Thanks!

 

Yep i will send it tonight.

 

sounds like black gmc really knows his **** when it comes to tuning. How long have you been using efi live black gmc?

 

a few years, it was actually my first mod i bought for my truck and i bought the truck new! But i had a lot of help from DC_justin over the years...
