Hey guys,

Looking to do some work on my 5.3l. Its an '05 sierra ext cam 4wd. Gonna start with a chip for sure, had a bully dog for a while but i couldn't access all the tune modes (Drive by wire?????? I was told, don't know much bout it tho.) Wanted to know whats the best chip for the motor. Truck has about 175,000 kms on it. But i wouldnt mind doing the intake and exhaust thing later on, so I need to know whats gonna be the best combo to run.

Thanks

Diablo is one of the best out there as in handhelds... Lots of people will say custom PCM tune.. but Diablo sport for your year truck has ALOT of custom controls.

I'm in the same boat here. I have the Magnaflow weld in muffler and have an Airaid tube on the way. I'm stuck between the Diablo, BlackBear tune and Wheatly tune. There seems to be a lot of info out there, but most of it seems to be opinion. I'd like to hear what someone has to say, that has tried all 3 of these options.

I have a scanner so i'm not too worried about that part of the Diablo, but with the custom tunes it seems that there are a bunch of options for the tune as well as ways to get a tune. If you don't know much about the custom tunes, it's hard to make an educated decision.

With that being said, I just sent Carlie Wheatly a PM. Hopefully he'll clear the air for me

I had the same truck just before i bought my SD and after trying Hypertech, superchips and pricing just about everything from EFi live to W4M, and Jet dynamic tunning but ended up with the predator. You can also upload custom tunes to it. If you need it. I had Nitrous and headers so i had to but other than that just intake and exaust predator worked fine. Just get it dialed in

Man first of all stay away from Diablo its complicated if you wanna go deep into it, and it runs about $500 extra to have a shop tune it correctly(I just sent mine back, I ran better with the hypertech max energy) again some shorty headers you can pick up a set of pacesetter for $269.99, cold air $300, helix$100, electric fans $500, and Pulleys $300 and that would be a great jump.

I've tried the Diablo (STAY AWAY) it cost me $370 to buy the programmer another $66 at radio shack to buy the cables that the programmer should have come with at the start, another $500 to get it tunned at " one of their certified installers" to fit the mods I have, not worth it!!!!

Yep. I've done a lot of research and I've found a lot of really poor customer service.

I have been in contact with Wheatley and we've been working out the details. I should have my tune VERY SOON. Wheatley's customer service is second to none so far

I should have my tune and Airaid tube installed in a few weeks, just depends on shipping times

I'll let ya'll know how it turns out.
