But your engine must have been pulling timing because of the heat, because your trap speed of 96.5 seems pretty low. You wouldn't believe what a difference a cool engine can make. Ice the intake while your waiting, this seems to work well with all motors, even if there isn't a lot of surface area to ice on the 4.6 manifold.
You can also think about manually shifting your auto. I know from my brothers '99 auto that the shift points are hardly optimum. In fact I think that the trans fuction is so bad, that I am going to make a wild prediction.
I think that my brothers car will pick up a solid 6 tenths after the custom program, and the MAF, pulleys, and TB. Thats a bold prediciton, but judging from my car and how my brother's car feels, I think its going to happen.
I picked up 6tenths w/ only a chip and MAF. Not including a better program from the dyno tune, U/D pulleys and TB that he'll have. Heck, since he has PI heads, he might do better.

Those are encouraging words, for sure! I KNOW my car is faster than that time, just from all the cars I've beaten on the street. Like I said, it was very hot, so it is quite possible the engine was being held back. I'll have to go back now that it's cooler. Thanks.
