The filter was dirty.. I'm actually cleaning it now. Weather was about as good as it gets down here.. clear skies, pretty dry, ~mid 70s?.... Shifting around 57-5800. Tune is updated, except theres still a problem with the new gears and tires. Throwing an ABS light still, but retune is on its way. Still a 99 PCM... Do you think that could be an issue? I'm using my 99 fuel rail w/ 05 injectors and 99 throttle cable. I went through the traps around 3700-4000 in 3rd.

yeah starts pretty easy. Once in a blue moon it will kinda sputter when starting.. but idles fine and no other issues. So you think I should request a newer PCM from Nelson on my retune?

Whenever you get a chance, post all the #'s on the slip it will help determine where something is going on. I'm sure trever1t or somebody with a similar weighted truck on the fastest truck list has a old timeslip you can compare mods/times.

Definitely not right. I've never weighed mine. I race with the tonneau cover on. All I do is yank the spare tire so I can mark my parking space. My best run to date (1/8 mile):
60 - 2.294
330 - 6.507
1/8 - 10.008
@ 70.77
A week later I went to a different track for my only 1/4 times to date. I can't find the slip right now, but I was disappointed with a 15.7. Not sure what was up as my 60s were a full tenth slower than at the 1/8 track.
Mods are below (minus the catback), stock 3.73 gears, 30" tires. I take off in 4wd so I don't have to scrub the tires (not that it's much of a problem anyway). The tune is by me and at this stage is mostly just fixing the factory fueling - I intend to start turning the wick up more this season.

Larger tire usually results in higher trap speeds, especially when he's cutting better 60ft times with the stockers. He's getting to the end quicker with the stockers not faster.
