Freakin sucks.
As a little refresher, I went to Allens a few weeks back to get a tune. Found out the fuel pump was crapping out on me. Prior to that, I had run a best of 14.87. That with the torque converter that was also crapping out and the Futral 218/228 cam.
Since replacing the fuel pump, I've swapped the Futral cam for a Comp 216/220, added the ported throttle body, and the homemade intake.
So it's a really cool night, and I head to Ennis hoping for low 14's. Totally makes sense right? Best of 14.87 with not the best or fully functional parts - seems like with the new stuff I should be kicking low 14's, high 13's in the butt.
Here's my times:
15.280 @ 90.60
16.008 @ 86.88
16.033 @ 86.87
16.235 @ 86.37
16.587 @ 84.77
16.498 @ 84.41
Notice the pattern??? Worse every run. I tried the first few runs in 2wd, tire pressure at 20 psi. Since it was getting worse, I figured I'd try a 4wd launch. Worse time - back to 2wd. Worse yet.
The truck is still doing the "bogging" thing at WOT. Get on it and it pulls hard, and then all of the sudden it will lag so bad it feels like you're on the brakes. Then all the sudden it will "Catch" and start pulling again. Then lag. Then pull. Then lag....you get the idea...
I don't know if this is a tuning thing or what, but I'm about ready to piss in the windshield fluid reservoir, crap in the gas tank, puke in the radiator, throw some sand down the dipstick, paint it with gasoline, and throw a match on it.
Somethings going on and I guess it means another 5 hour drive to Allens and another day off work. Not cool. Not happy.
