Yea that was right after I put the Doug Thorley Tri-Ys on it and had bumped the VE table and MAF tables up about 5%. It was literally open exhaust after the Thorley head pipes in this log too.
Post retune it is alot leaner and meaner! I actually had to reduce the MAF values after headers because the headers richened the tune up so much from the added airflow.

Ok guys just got back from a 1200 mile roadtrip up to Lake Tahoe (high altititude). Truck feels good and shifts great! I had many hours on the road to get used to the converter. I notice that when I'm going down a grade, the converter will lock/ unlock, lock/ unlock continuously. What's up with that? I've read that it's normal and there's a way to eliminate that in HP Tuners but do I even want to eliminate it? Also, I notice when the truck downshifts out of OD, it's like a 2 step downshift, first the converter unlocks and then the trans downshifts. I've also heard that this is normal but wanted to mention it nonetheless.
I also dropped the pan last night to check the fluid, which looked great. I changed the filter since I didn't have a new one when I did the valve body mods and the trans shifts even better now, perhaps the old filter was a bit clogged who knows. I can't wait to put some power through this thing!
