They are right about the predator tune, it does not remove TM and still allows the ecu to pull timing, it's a liabilty issue. I went from 370 rwhp to 388 with high flow cats and 1 7/8 lng tbs. your air to fuel ratio should stay around 12.8 all the way to red line on a dyno pull.

You need a tune, that's where the power is. The first time I punched it after adding headers I said "****". There was a very noticeable gain on the top end.
