Thanks! I think alot of the reason it's running so strong is the 50 deg IAT temps. The high to day was 28 deg. I know the timing is too low and the rich AFR is hurting me, but It's safe. Im going to leave the timing and AFR alone, and try 15 LBS. You can get away with 3-4 psi more boost up hear @ this elevation than @ sea level. Draw back is that you need an additional 3-4 to get your sealevel HP back. The cool IAT helps also. How much boost, and timing are you running down there? Thanks, J

T76 vs T66
I just swapped the T66 for a T76 that I had lying around for another project, and all I can say is WOW! At the same 12~13 psi there is a big difference. My AFR has came off RICH and read 10.5 for the 1st time.
That just shows how much more air the 76 moves @ the same psi. I just couldn't help myselfe and had to give it a little twist and see what 16psi would do.
The thing is about dangerous. It breaks loose @ 25-30mph in 4wd, and tries to yank the wheel back and forth. Now no one will ride with me now so it's difficult to get a log.(piece of **** vista)
It's hard to watch the road, AFR, boost gauge, and computer all at the same time, with all that going on. I did get 6 deg of KR at the top of 2nd beg of 3rd. Power fell off big, it did it once getting on it @ 40mph even before boost came in
. Also did it a few times last week at 12PSI. I can't hear any det at all. The AFR is 10.9-11.2 @ wot. The T76 ripps, but the lag is horrific. Takes like 3 full sec to spool, then all **** breaks loose.

I did order a .68AR housing today. That knuckle pisses me off, thats what happens trying to work with cold hands. 
Started bleeding while I was asleep. Got blood everywhere. Starting to hurt now, couldn't feel anything when I did it.
