I recently installed a Vortech SC and Alpha Werks headers on my car. I have had ZERO custom tuning done to it. So it is just running the stock program from Vortech. I am also just running 18" street tires. I have run on 2 different occasions. Both with decent outside temperature. But the best I have ever done is a [email protected] with a 2.117 60ft time. I thought maybe it was me, so I let my friend drive. His best was a [email protected] with a 2.125 60ft time. He is 100lbs lighter than me. Now what I have been reading here is that guys are running [email protected] So my question is, what is your secret? And if you have no secret, is there something wrong with my car?(SC or program or tuning.)

:banghead:

What else have you done to your Z? What kind of wheels? Maybe the street tires are not hooking up for you that well. :dunno:

Daking with his TT kit was getting better times than that, but he's done a lot of internal upgrades and mods to the Z. Maybe you should take your Z to a tuner or think of a couple of other things to upgrade. Does your SC kit come with any other upgrades?

thats really bad times. you should go to a dyno at least and see what kind of hp the car is putting down.. i have seen 3 vortech supercharged z's and the hp range was 375 to 388. so if your way under then you should have it tuned i would think.

Yeah, thats what I thought too. But I wanted to ask around before spending a ton of money on tuning.

No, I am not sure. Everything is connected correctly. I get 7-8 psi on my boost gage. I need to go back to the dyno and see exactly what I have at the wheels. Then I will call Vortech again. It is very upsetting because I know Vortech makes a good product. I think I just may have got a bad one this time. I have the name of a tuner in chicago. After everything checks out and Vortech says they can't do anything about it, I will go see him.
