Reasonable mods for 91 gas?
So we only get 91 octane gas here in Cali, and that really rules us out for running map 2 in BMS JB4. Does that mean a Challenge HFC DP and a Stage 1 BMS tune is pretty much going to yield the same power increase as getting JB4? Maybe marginally less power...

Still get the JB4 - It's a much better integrated tune and even on map 1 you'll be ~1.5 psi over a stage 1
Other things you can do with JB4 stage 2 you can't do with stage 1
The install takes about 5 more minutes than the stage 1 and it doesn't cost that much more. Make sure to get the USB cable as well so you can update the flash as terry releases new ones |
