Can't actually answer what the HP difference would be for you. But I just recently switched from an Autothority chip to Steve's chip and there is a major difference between the 2 chips. IMHO
Low end responsiveness is much much better w/ Steve's chip and the power seems to be there all the way up to red line.
But when I had the Autothority chip in it seemed like it took more to build power, then @ 4500 rpm it felt like a turbo kicked in to red line.
I ended up using a friends LM-1 to show my A/F ratio's and as it turned out, I was running way too rich w/ the Autothority chip.
I am hoping to get out this weekend to run the LM-1 on the car w/Steve's chip in there to see the difference.
Overall I just wished I had changed to his chip much sooner,the car runs better and stronger than ever before. Steve is a great guy to deal w/
and he can always re-map the chip for you as you add parts.
