Well just glancing - your imrc's are probably opening too late and your running way too low of timing - you could add 10ish degrees more at full load and do a whole lot better - that's if you have headers, exhaust, cai, tb and so on... Your cam tables could use some work too... Do you have any dyno charts as of now or are you tuning on the street?

I installed cams,phaser limiters,long tube headers, cat deletes and had a base tune from bama but couldnt get it started was really rich and put stock maf figures in and started just fine no problems just when underload im thinking my imrc's aint oppening at all but have no codes to speak of ive mostly done ls1 and the fords are new to me this is my first mustang ive owned my other weekend cars are a cammed ls1 s10 and cammed ls2 1986 325i

well i did some more tinkering with the tune and is running real good idle and wot but when shifting gears at 20 to 25% throttle while cruising kind of backfires and stutters and give it some more throttle and goes away
