Which next mod would benefit me most?

[trikeffex]

Hey guys, I have a 98 gt with PI head and intake swap. My other mods are in my sig.
Im getting a dyno tune this Wednesday. I was wanting to know what mod would benefit me the most. Im looking for something to give me a faster 1/4 mile et. What would you guys reccomend? I have thought about cams and valve springs but i am unsure. I have also thought about a small shot of giggle gas. thanks

If you want cams you better wait on the tune. It would be best to get the tune after a cam install. You've almost run the limit of meaningful mods except for a blower...if anything I'd save for that.

I'm not a big fan of nitrous but only because of the horror stories of blowing things up. Of course thats part of the fun.

long tube headers and matching h/x pipe. this is your best choice trust me you will see some good numbers if you still have the stock manifolds
