Hey guys, I'm new here and just wanted to post my experince with Wheatley tuning. Shipped the ECM on my 08 Sierra Denali to him on Sat and he had it back to me on Tuesday ready to go. Plugged in with no problems and I'm happy with the power. Sucks, though, that I couldn't get the Torque Management out of the trans because the TCM is inside and can't be mail order tuned. Every time I e-mailed him he got back to me promptly and even called UPS for me when we realized they sent it back to the wrong address. Thanks

 

Glad you like it!

TCM inside the tranny. That's what Nissan did with the Titan and it sucks big time.

 

+1 for Wheatley! Awsome tune, night and day with a Wheatley tune!

 

Yeah, I'm going to have him live tune it in a couple months. The Torque Management is really holding this thing back but it's still a beast. Has a lot of potential though.

 

give it some FI and the potnetial will be set free! post some pics up. and Welcome to the site.

 

I would love to go FI but I don't have the cash right now. I'll probably do a Magnacharger later on though. Will be doing headers soon as well.

Is there any way that I can post larger pics on the site? I have plenty of them but don't want to shrink them all down so you can't see anything.

 

Not sure. I end up using photobucket...

I'm sure others will chime in.

What motor does yout Denali have? What's the specs??

 

It's the 6.2 with the 6L80e trans. 403HP, 417TQ should be more now with the CAI, exhaust and tune.
