you should have had the FP internals way before you were fully bolted, like when you did the downpipe.
If you want an AP and are not within the range of a shop with a dyno that KNOWS how to tune a MS3/MS6 that has the protuner license for the MS3/MS6, your only choice is to run an OTS map. With an OTS map, it seems like the only people benefiting from the AP are people with the exact mods required for that specific map. Anything different throws the tune off, hence why the OP just said he was backfiring, running like s***, etc. The standback, right now as it is, will not necessarily get you more power if you are fully bolted. The car does not respond like that. What a piggyback like the standback or XEDE will do is get you solid boost control, get you out of the 9-10 AFR's, and the built in ability to control meth.
It obviously is beneficial to lean the car a little and make the AFR line nice and clean at WOT, but there are a handful of people, fully bolted BT only running the CP-E flash with a MBC and making just as much power as the 'tuned' guys. Nobody has quite unlocked this ECU yet...
