Do you have a base line, other than the stock numbers from gm? I'm not sure on hp numbers, but I would guess you'd be running mid 14's @ around 94-95mph.

 

thats pretty good but only mid 14 with the rest of the mods i have in my sig is alright

 

Don't forget about chip burning. You can add all of those things and you will run SLOWER if you do not get a cutom PROM. I am friends witha kid on the board here who has everything done to his 305 and we are struggling with the tuning and the car was faster stock than it is now.

 

i already ahve a chip on stage 2

 

The stage 2 is not a custom prom. You will need a custom prom to get your combo working to it's fullest potential.

 

do you know anyone in south florida who does custom proms near miami and how much will it cost me

 

Best thing you can do is to burn one yourself, or find someone in your area with the equipement and experiance to help you. Custom chips such as Ed Wright's run over $300. An inexpensive alternate is http://ww.tbichips.com .

Also check out the DIY Prom board and take a look into the the Prominator. Very, very awesome stuff. I think it is nearing completion, and my be released before you finish your mods. I can't wait for it!!!
