data logging:
i plan on doing 3rd and 4th gear runs up to about 6,000 rpm. thus, i think i will be doing like 120 mph or there abouts.
I live in a small town in south america, the highways are narrow and not many long straights.
120+ on these highways is not that easy.

I do not have a proceed, so I must manually data log my boost levels.
IS IT A BIG DEAL IF I DATA LOG WITH 3 TOTAL PERSONS IN THE CAR??

I would drive, another would call out the rpms, and the third person would record my boost.
Having 3 people in the car will not affect my boost readings will it?
also, will 3 people in the car affect the total timing advance log i will run on my auterra scanning unit?

i am new to this kinda stuff, so thanks for any input

14.5 psi regardless of which gas your using.

JP's log has his at 14.4 at 5000 rpms in 3rd gear and then tapering as it should.

Maybe He bumps to 92 it could be 14.5 or 14.6?
Keep in mind this log is in 20 degree weather. Warm weather it may read higher.

I say be happy with 14+

Unless I'm missing something, the engine puts out the same amount of power regardless of the curb weight of the vehicle. So the answer is no, it doesn't matter how many people you pack in there LOL
