people say to go straight to stage 2 because you'll get power hungry and want more.

I had stage 2 in my 135 and loved it. but I had meth. stock fuel system (only 93) will run you into 450ish whp range. expect to add supplemental fuel after that if you're looking to keep things working right. I had meth in my car (kit still for sale )
I think to get more whp, you'll need to increase the engine size. My dad's 496 stroked big block only uses 93 octane. We will add a supercharger this spring and still only use 93 octane. I'm sure you can get around 500ish without the need for meth.
