help me get a decent tune before dyno this summer

[dsmreck]

ok I bought this car and the last know tune was in 2008 done by shane.
The car is a 98 w/ 4g64 bottom/ 1g 4g63 top, bc280, port head, forged everything, pre 1000 on e85, no pcv, just has a catch can with filter, gm maf with maft, ecm 2.5. I just used the tune I had for 522 @ 22lbs.
here is my idle log.
