I would wait until you have some more MODS. I did the ECU chip when i had a decent amount of mods and i did not notice any change!! Buy a set of gears, it will be the best $$ you have ever spent..
Do you guys like the out of the box cams? I have never really had good luck with them. I have a custom ground camshaft innovations cam in my car now and i love it!
But back to the original question...the gain could be good possibly but it depends. Maybe with the cam yes, more timing down low would help out. There are a few different things.
