Just ordered SCT SF3 Tuner and 4.10 combo.
My JLT RAI should be in before that. Can't wait to see what the difference this will make.

EDIT: just canceled my order, didn't realize the difference between the SF3 and X3 tuner. I rather have a custom tunes that accomidate for me. I'll order the X3 from AM and get custom tunes for life. :-/

 

I got the AM x-cal tuner as well I didnt notic a difference with just the intake and the tuner, but youll love your mach1 with the 4.10's that was the best thing I ever did to mine.

 

I bought some NIB FRPP 4.10's (actual FRPP ones not the crap ones made by Motive for FRPP) from my buddy but need the install kit from AM...I was going to get them installed fairly soon, but my TOB decided to be a b!tch and make noises so now a TOB/clutch/pilot bearing is being installed tomorrow plus install costs...

4.10's will have to wait...bummer.

 

Ouch, sorry to hear it bro.

I can't wait to throw in the 4.10s myself.
