My bolt on GT first time on the dyno. I put down 258rwhp/314 lb ft on this run. UPR X pipe and Mac Flowpaths are that sweet sweet sound you hear.

  • Good #'s. I got mine dyno'd this week and am making 258 and 292. Wheres all your tq coming from? They said my car was burning too rich but I don't have a programmer. Supposedly thats costing me some numbers.

  • Thanks man. I was suprised at the tourqe it was putting down, but I am a little skeptical it was actually making that much. It does run strong though.

    You are better off running a little rich than too lean though. Mine was lean at 13.6-13.8 AFR, I had to bring it down between a 13.2-13.4.

    Programmers are a good investment. I gained 7rwhp and 13 lbft with mine adjusting the tune, and I also used to to calibrate my gears and shut off the CEL for my exhaust.

  • Hey man message me up wit home pics of the dyno sheet. I'd like to compare the graphs. I see the tuner helped your TQ quite a bit more then. Nice sounding BTW.

  • Thanks man. After I read this message I tried to find the sheet but I must have mis-placed it and I didn't scan it after I got it.

    I'll keep looking and if I find it I will send you a copy.

    I do know that I gained 6.9 rwhp and 13 rwtq over the canned Predator tune though. I was real happy with the tourqe increase.

see all

  • Staying N/A 4.10's are great. 3650's have alot of issues. Some break and some dont... Tranny's arent the strong point of a Mustang unfortunatly.

  • 02. I got the T-3650. It's had to be rebuilt already and ive only got 44K on the car. I don't like the tranny, so you think that 4:10's would be good? i'm going to stay N/A

  • Nope. The only other ratio I would go with is 3.90's, as they are a great compromise. I almost went with them, but decided on 4.10's at the last minute. What year is your car? If its a mid-01+ you should have the T-3650 transmission. Its 5th gear is better suited for 4.10's and cruising than my T-45 is.

  • you wouldn't go down to 3:73;s would you? i cant decide what gears i want. I'm buying them this week

  • Nope. It has a K&N intake, 75mm TB and ported plenum, X pipe, Mac's, and a Diablosport tuner for power making mods. Also have 4.10 gears but they dont add any power, sure feel like it though... hah.

  • is that all you have done to it?
