I'm running an RWTD tune. I haven't had it dynotuned yet. I ran at Englishtown last Thursday. That is strange. I was trapping 119-121 throughout the day. I know i was getting a slight hesitation on my 2-3 shift, but i don't think it will affect mph that much. It pulls harder down low than when the same setup was on my friend's car. The difference was he had a 12" filter and magnaflow catted-x. Is it possible my 9" filter is limiting me at the top end?
my full mod list:
stage 4+ port
2.65/2lb lower
steeda cai(only a 9" filter)
sct ba-2400 maf
60 lb injectors
mrt catted-H
magnaflow catback
spec 2+

yea get it on a dyno and see where things are at.
i would mention to james about the hesitation and after he views your dyno run he can more than likely see how to correct that.
i doubt your 9" filter is hindering your top end speed as i'am using a 7" filter on my jlt cai setup and i will trap 121.3-121.7 nine out of ten times.
