The significant difference between the two chassis is the stock boost. G chassis applications run a much higher boost.

Back to the recommendation

Running map 5, 22 PSI on the F chassis is a considerable PSI increase. You should only do it if you are running an E85 mix.

Running map 5, 22 PSI on the G chassis is not adding much since the stock application can reach up to 20 PSI on its own in optimal conditions. You do not need E85 in this case.

No matter which map you run, send the datalog to BMS for map approval.
Thanks for the explanation. It would've been nice if BMS had explained it like that on their website.
