Yeah I just need a baseline for S&G’s. I could just do it all and then get it dyno’ed, but I’m just curious.
I know I don’t ‘need’ a tune, but it’s recommended even for a stock car with these motors as it’s said that it helps them be more efficient. My friend (who has a 6spd, VQ35, turbo’ed + other stuff 96 Maxima) said that the plenum will help and that it will become more efficient:
It might actually change your mpg as well since nissans tend to run rich ( more fuel then air ) from the factory. And the ecu will compensate to a certain extent with more air flowing. However you are 100% on Uprev doing great things to the vq35. Just wish it was an option for the maximas. But you will not need a tune with just a plenum spacer.
Funny thing though after my tune on my 4th gen, my mpg went up if I drive the car normal.
I’m trying to squeeze every ounce of efficiency out of this motor that I can :lol.
Here is his car:
