Finally got a chance to go to the track Piedmont, NC 1/8 mi. I love it I know where Im gonna be every thursday. First off on my way out there I plug up the laptop and get a new code absolute manifold air pressure P0107 (i think) I have kr all over the place and my lt's are all out of whack. Then I start hearing some pinging when I gave it throttle. Now Im worried. I figure its a vaccume leak hopefully not intake gasket. Its intermitent sometimes truck runs stong and its not there some times it is there.

Anyway I decide to press on, get out there and me and couple buds look it over it all looked fine except for some loose fittings. Let her cool off start it up and its not there ok race time

1st pass 4wd switching to 2wd about 50
r/t .768
60 2.177
330 6.035 @ 16.31
1/8 9.267 @ 77.02

2nd pass 4wd all the way
rt .818
60 2.138
330 6.057 @ 16.18
1/8 9.344 @ 75.76

3rd pass 2wd 20 psi shifting at 5900 small amount of tm still in
rt .807
60 2.025
330 5.816 @ 17.72
1/8 9.020 @ 77.59

4th pass 2wd 20 psi shifting at 6300 no tm
rt .787
60 2.094
330 5.902 @ 17.13
1/8 9.110 @ 77.37

I think my setup has a high 13 sec pass in it. I had 2 degrees of kr on the last run (the only one I got to use hp on) so Ive still got some tuning to do, also have that vacume leak, Ive also noticed the higher the tranny temps the less it likes to grab shifts and the stall seems to suffer it just feels different. So tranny cooler, ud pulleys and some tuning are next. Then I want the spot only na 5.3 ext cab z71 running 13's

The only weight reduction was the tailgate still had the spare on and all my **** in the back seat. Im figuring the truck with me in it was around 5500 pounds 5300 for the truck 250 for me.
What else should I need to get me to my goal of 13's

I believe that 9.02 would get ya real close to a 13 sec slip

The stangs where in full force got to race a newer one looked like an 04 I beat the guy on every run he was pissed, I know he was slightly modded exhaust xpipe intake and a chip. He saw me messing with the laptop and came up to me saying "you dont need that you just need this(pointed to his head) and that (pointed to the engine)" I sayed ok
Then I ran a 9.020 and he was at 9.2 I tried to give him a thumbs and he wouldnt even look at me after that. My friends thought it was pritty funny. With an eaton and ud pulleys I should be into the 13's

with your 1/8mi times i'd say you should be around 14.20's in the 1/4.

1/8 9.17@76
60' 2.09
