    Here you go. My car is tuned again. The new and old dyno graph on top of each other 4 U 2 C. I made a bunch down low and up top. Last dyno session I had the stock gear, this has the 4.10. I had the tune done with the knock sensor kept on. The outside air temp was in the low 30s. The tuner said if it were warmer it would have made a little more because the correction factor is so strong in the cold. Now for the bad, My poor o2 sensors are not liking the new set up and need to be replaced. But my fuel milage will go up after the new ones go in. :beer::beer::beer::beer: How old are all your o2 sensors?

    Mine are about 2 1/2 years old i think? or 1 1/2. I think the first though. Either way, one or both of them isnt working anymore because I have the beautiful check engine light on constantly, hoping to get a tuner this year and turn them off.

    My rears are turned off. But the fronts are the ones that are not liking the Long tubes. They are the originals. Its time for a new fresh set. I hope for a little better gas milage.

    Pretty good numbers for a Dyno Dynamics dyno.

    That's a result of the dyno dynamics dyno. Those numbers would be lower on a dynojet.

    They are all different, but I've seen them read higher by as much as 10%. Most aren't that much higher.

    I have yet to see anyone that was getting a tune NOT need new o2"s just something you should prepare for when getting one it seems.

    Guy I work with sold his 2003 Mach 1 awhile back, and just recently brought me in two spare Bosch oxygen sensors that he never put in, brand new in box. Bosch part #'s 15716 and 15717. The plugs look the same, just a difference in the length of the wiring from the plug to the sensor.

    I remember talking to you via PM awhile back about some exhaust parts, we're both local in Chesapeake. Lemme know if you would like these. I have no need for them, would let you have both for $70, or whichever you need for $35/ea.

    Nice numbers by the way. I'll probably be getting a baseline done on my '99 @ DTP when the weather warms a bit.

    with a tune cant you override the sensors and turn them off, and just put plugs in the holes?

    A 70 ft lb improvement at 3000 rpm just with headers?

    Is that correct?

    yes you can
    It's the dyno. It's like a Mustang Dyno providing low numbers only opposite. On a dynojet the hp/tq would be more in line with cars with similar mods.
