falls flat on its face before 60..

just had the jeep serviced and had the fastman throttle body as well as the magnaflow 22" muffler installed on it. i notice my jeep flies through the gears and hits 5th/OD before 45mph. she seems sluggish before 60, then after 60 its all downhill and she rolls. im wondering what i can do to help this. i am going to take the resonator out of my factory air box, but i was wondering if a nice drop in would help this?

Re: falls flat on its face before 60..

Well #1 bud, it's a 5K LB 4.7 with 255/75's..... so thats an issue...

I'd have to feel it compared to mine. When we meet up next week, we can compare, see if yours is different from mine.

I have an intake, Flowmaster and a superchips tuner.

Re: falls flat on its face before 60..

I think you're not at WOT bud... i tried it today and got a vid. I'll post it when i can. I got to 60 at around 4300 RPM in 2nd gear.... in the rain.

I know i have a superchips that changed my shift points, but i just dont see any way i could even shift through 5 gears before 60.

Edit: haha i have a vid on my phone, but i dont think i can post it, seeing as my computer here at work doesnt support it. sorry
