I can't guess how much you will gain, but I would say that if the tune is right-on, then your can will run much smoother, and you will probably feel a nice SOTP difference. Tuning is definitely worth the money with the mods you have. Make sure someone who knows their stuff does your tuning. Good luck.

dyno tuning would be much better with your mods. dyno tuning is definitely worth the money.

with a dyno tune and my CAI / LM I got 12.3 rwhp. (so actually add that to my numbers down there). but i wouldn't necc. expect that off hand. i'd say wait for a tune till you get gears or a cam.

A dyno tune is the way to go.
I had Ed Wright (Fastchips) program my PCM and he does good work. When I put a new motor in next year I am going down and have him dyno tune it for me.
I also think you would see 15 to 20 hp with a tune.

I gained 11 HP with pcmforless, a KM and an airfoil.....I
m assuming about 10.7 HP was because of the tune.

On a stock car probably not much. 10-20hp maybe, and that's stretching it I think.
On a heads/cam car who knows...I've seen guys pull out 55...maybe 70hp!
