i might be running mine tomorrow...  89BLackTGP how are you launching man just droppin the clutch?  What rpm?  Boost?  A lot of spin?  Let me know im trying to figure something out, have my boost controller rigged for lower boost off the line to help traction, then closed for 2nd and on.

Well I didn't want a failure when launching so I kept the RPMs low. I slipped the clutch as
much as I could at around mmmm maybe 3,000 and after the tires initally started to move I punched it and fully let the clutch out. The tires still spun a little doin it this way but it was a mix of traction/spinning. It chirped 2nd good and hard. I ran potenzas 009's on the front. I usually have proxes 4's all around.

I would be afraid to just dump the clutch in case you doo hook and then snap axles. This was my first time running a 1/4 mile. Once I go again I will probably get more agressive and get better times. My worse part is taking off.

I wouldn't start judging chips yet Jon you have to remember I have been pulling things out of my car for weight reduction that most people wouldn't and I'm still not done with that. plus tires have a lot to do with racing summer tires are better than run of the mill tires and the M/T et streets are not too much of a durastic change they just help keep wheel spin to a minimum off the line.

Search his screenname - "sleeperred90tgp(RIP :icon_sad:)" on here and you'll find info about his car. He had a larger turbo, top end swap, etc. on that car. It could have been WAY quicker had he actually had it tuned properly.

It was interesting to see how a topgun chip stacked up to a flybynight.
IIRC the best anybody has done on my tune was a 14.2. No weight reduction and a stock turbo. The only mods were a free flowing exhaust and some 28lb injectors...  It was an auto as well...  :icon_biggrin:

Hmmm..... 14.2 with no weight reduction on one your chips Flybynite? How much I'd like to see the difference in my car. but I still need to get a hold of some LS1 valve springs then actually get around to installing the Rockers. Shoot me a Pm on a estimate for a chip please :icon_mrgreen:

Looks like you guys need to block the rear struts and keep some of that weight from transferring to the rear. ;)
