Yes, you can. 
Every time I have tuned my MAFT with ATAP, its always perfect 13.0 on the dyno. Maybe I just get real lucky... IMO it's possible. With LT's ur probably lookin at 8-10% lean for the WOT setting to get ur air/fuel back to where it should be, but use ATAP.

Yes,you can tune with A-tap and MAFT.Of course your limited to just A/F adjustments.
Ussing A-tap tune in the L-terms ussing the base switch.Try to get them -8 to 0 the best you can.Remember base setting affect WOT so you need base set first.Then you can tune WOT by reading KR and A/F.I shoot for .89 to .92 on the 02's in 4th gear.When close make sure there is no KR.
Another way is to tune till you get KR then add 4% fuel.
