you would have been better off just putting in some catless mids ,on the black ten of mine after i install the comp 270hr cam just dropping high flows for catless mids netted me 25hp ,with your 3 in and no cats you would be better off :rock:

I had Excessive Autosports in Sioux Falls, SD tune my truck which was on a different DynoJet Thursday and it made a little less HP 479.23 and a little more TRQ 507.03. He added pic's on his web site and he might add the dyno run to. I'm happy with the way the truck running with his tune.

More accurate numbers honestly based on my experience. If he wasn't monitoring A/F how did he tune it?:dontknow:

He was monitoring the A/F on all the runs and dose a lot tuning and knows what he is doing. He just don't show the A/F on his dyno sheet.

OK, so where are your ratios at on your tune?
Cheers!
Driving the truck I see mid 14's and at F/T I see mid 12's on the A/F gauge and the truck is really running good.
