Installed a Magnacharger, 3.3 pulley, 90mm LS2 TB, E-Fans, stock cam, Outlaw CIA, Pacesetter longtubes and ORY, Flowmaster American Thunder. This is on an '03 Avalanche 5.3L, with 20's...

Pulled 377RWHP and 429RWTQ after three pulls it over heated big time, found that my mail order tune not only was set up for 26Lb injectors (hench halfing to take it to the dyno shop and have it tuned) it was not set up to run my new efans as it was supposed to be either

Did get to make several in the truck on the street runs with the tuner and HP-tuners and it runs very well now.

I'm pretty happy now, was pretty scared when I tried to run it with the first tune...

 

Cool, glad you got the problems worked out. Did you make the 377 hp with the bad tune or the shop's tune? Any dyno graph available for posting?

 

Congrads on the new setup and newfound power!

 

Truck was running so rich I don't think it could have made a run. Loaded up so bad it looked like it was a diesel under any load. The run was after the tune was repaired.

The shop didn't have a disc to copy the run to. I have a hard copy. I'll try and stop by the shop on Monday and bring a disc. They tuned a vett today that was supercharged 500hp, and they are now an STS dealer they had a '07 Vett that they are going to install the twin turbo set up on. I'd like a ride in that one!

and thanks, the truck finally runs like it should..

 

just wondering who did your first tune?

 

I am waiting to here back from the tuner to see what he has to say, I'll Pm you, but would rather not post until he has a chance to get back with me.
