    Hesitation at start-up.

    What mods do you have? I have experienced symptoms like this sometimes. It is because of the long tubes headers and the placement of the o2 sensors. They take longer to get to temp since they are farther away from the engine. Some people with just and offroad pipe are having similar problems...

    car smoking...

    Smoke or steam? Burning coolant is usually easy to determine. Have you lost any coolant? What is the temp there? Also this is normal if you have not lost any coolant and it is cold outside. This is most likely just condensation in the exhaust. The cats convert HC and CO into H20 and Co2...

    Billet Grilles...

    Shelby will be releasing the GT350H grilles in the next two months. Someone also needs to make a kit to either relocated the factory fog lamps or sell a relocation kit with smaller fog lamps. Does anyone know of any companies that have a kit with smaller fog lamps and a harness that you can...

    Tuning question for experts

    I reverse my previous post, I did not realize that you were talking about a GT500. I was thinking of an S197. 33RWHP is definitly realistic. Hell the 03-04 Cobras would pick up anywhere from 20-45 RWHP on just a canned tune alone. Sorry I misread your post.

    Tuning question for experts

    For starters that is a tune that is most likely for 93 Octane. Ford tunes the cars with conservative tune(I'm guessing). Both on engine and throttle settings. They have definitly left plenty of power on the table. I don't see 33 RWHP on a stock car with no mods except the tune.

    need help frpp 4.10 gear issue ?

    Not always that depends on the difference in manufactering between the housing and the pinion. That is the nomial pinion shim to use no add to the stock one. That is why there is pinion depth gauges and there is also several ways of checking pinion depth.

    need help frpp 4.10 gear issue ?

    From talking to tommy from JPC, the rear end is the same. Except for a few small differences where the control arms mount upper and lower. He said that they have had some cars that were very difficult to set them up without noise. While others didn't have any problems. It took me three times...

    07 GT hp upgrades

    GT500s are sweet but heavy and overpriced. Though I saw that vid from evolution performance running 9s with no that many mods. It would have been nice for the car to go for low 40's.
