Yeah I'm going off a dimly lit yellow screen that flashes three times then turns green. I thought the fastest reaction time you can have without jumping the line is .50 or am I mistaken?

Torque managmant is whats killing you, get a custom tune with the ported throttle body and cold air, pacesetter longtubes and ory. i ran a 15.30 with just a cold air. Now i have done camswap, ported throttle body myself, 100 shot of dope, dyno tuned and a heavy ass right foot. waiting on LT's,ORY and converter before i spray at the track, hopefully mid 14's maybe...Im gonna take it back to the tuner after LT's and get the spry tuned in.

I don't know what the best is, but I cut a .006 last wed night.:D

I checked Texas Speed and they have the Pacesetter longtubes for 400 which I think is a damn good deal. It says its for 99-04 which I believe will fit on my NNBS correct? As for the TM, that is the ultimate limiter on the NNBS and I'm going with the custom tune but it wont be for another two months or so, does anyone have any better info on where to get my throttle body ported and polished?

Well hopefully getting my TB ported and polished next week (found a shop here in town that'll do it) but thought I'd throw it out there that my K&N and my TB came in yesterday so I threw them on and took the truck out for another 1/4 mile run using the programmer and with spinning the tires a bit pulled a 15.27 @ 93.3 MPH which before with just the programmer ran a 15.41 @ 91.3 MPH but I could feel the difference seat of the pants but it's nothing to big, felt the difference more in the midrange. Also looking into a set of LT's and ORY and hopefully after that it'll throw me in the low 15's or if I'm lucky drop me into the 14's (all I can do is hope haha). Anyone have any info though on underdrive pulleys they could give me? I'm not familiar with them.

you should be ripping into the high 14's

RIPBOYD 04-24-2008 09:36 PM

I should be ripping into the high 14's right now or after the headers and ORY?

Is there a track you could go to. I would be interested in seeing how the numbers compare to an actual track time. Just wondering how accurate the programmer is. If it is real accurate, it would be a good tool to test new parts with even if you decide to get a custom tune later on. By the way, those are nice numbers your running.

RIPBOYD 04-25-2008 07:19 PM

You and me are on the same page outlaw. I'm waiting for the next test and tune at the drag strip we have here in town and then I'll get to take the truck out there and run it on the tracks numbers and see how they compare. I'm curious to see if it would run faster or slower out there, it would be on stocks though not on the 22's it's on now and hopefully they wont spin off the launch. Thanks though on the numbers, I'm planning on running the programmer on the 4th level tonight (the "extreme tune", I've been running level 2 the "econonmy tune") and see what kind of difference that makes on my time if anything at all. I'll post back up and let you guys know.

Hopefully you wont smoke those stockers now with the extra power. Keep us posted, I am interested to hear the results.
