9D4Z28

I have a 94 z28 with magnaflow high flow y with cat, morrso Cai, and GmmG CB. I know I should have headers if I want a real gain, but I'm a college kid and can't afford it. Anyway how much HP could I gain with a dyno tune? Thanks in advance.

If you can afford a dyno tune you can afford $300 for headers from ebay... You might get 15hp on a tune alone "might"

The more mod you have the more you will gain from a dyno tune; as your car is now it will not be worth it, you will gain about the same with a mail order tune like pcmforless.com. If you plain on doing more mods I would do more before I did a dyno tune

I've gained 1.1 mph in actual track time.

BUT if you factor density altitude correction on before and after runs it's a gain of 3.5mph.

My mail tune was giving me 8' of knock and a sub 11.7 AFR.

This wasn't a dyno tune. It was butt dyno tuned and track verified and track tuned too.

I still have some work to do. The afr was ignored (sloppy 13.0ish) and I still had 3-5' of kr on my best run of the night.

All in all I'd say that's pretty goddamn substantial so far.
