there are a couple good tuners out there, you call them up, give them your mods and they have a vast database of info on tweaking the computer program.

and NO the dealer won't do it

some places to look into are:
madwolf from this board
www.pcmforless.com
www.tbyrne.com now has a tuning company (new...don't know much about them)

post in the NE forum, somone may know of a place for a good dyno tune.

where in ny is woodhull? i grew up outside syracuse

 

Woodhull is about 20-30 miles west of Corning/Elmira....."the Southern Tier".......just a little community in Steuben County, mostly known for the 3/8 mile dirt track and 60 miles from Watkins Glen International.

My folks are in Silver Springs, FL....they spend winters there.

 

I think the cheapest would be air in and air out...lid and catback. Then some et streets...but before you so too far...subframe connectors (i.e. Kenny Brown dd's...)...

 

Normally I would say lid and catback, but since you already have those, then I would recommend:

Pacesetter coated longtubes and y-pipe (Use the flowmaster collector instead...See LS1tech for the post and pics)

OR

Nitrous. The NOS dry kit is around $550, and there are cheaper dry kits (that only use one solenoid - hence the cheaper price) on ebay. I am putting my own dry kit together and it's turning out to pretty cheap. I'm suggesting dry here simply because it fits your budget.

You can knock .2-.3 with the headers or an entire second with the nitrous off your ETs.
