I HAD some Hangar18 mods, such as increased diameter power valve orifices and a boost referenced power valve, but not all of them, and frankly, I felt like I had screwed up things so badly that I took the cowards way out, decided that I would simply not drive this car on the street, so made it into JUST a race car.... so, that made it possible to do the easy thing (and, forgetting about driveability "manners," and gas mileage,) just remove the power valve, entirely and raise the jet sizes by 10....
It worked well, and gave me the A/F ratio I needed, so, NO, I don't utilize the Hangar18 methodology at all, but my car would not be something you'd want to drive on the street; unbelieveably-miserable gas mileage, to say the least! :banghead:
