My DYNO results are in.

I agree with Cody, you are looking at about $4000+ for an extra 43 or so HP. the cost of HP upgrades increases exponentially relative to the amount of gain you get. Personally if I had $4000 sitting around I would be buying stocks or paing down my truck loan. That's almost half what I paid for the truck
Though I would love to have both of those mods too..

If doing one I would go with the injectors and a HPOP upgrade then you can shorten pulse width and up the pressure and get better atomization and even improve fuel economy as well as more power so there is benefits on both ends of the economy vs performance spectrum. at least that s my understanding

Thanks for posting the dyno results though, we have almost identical setups so it gives me a good reference... The emmisions test here does it at 30, 40 and 50mph and my recent test with the 60 hp superchip gave a best of 244hp. which is probably not peak but a good reference point
