cause there is no reason to run richer/leaner. you make the most power w/ 12.1-12.5 AFR. if the stock one doesn't run that, then you can get an adjustable fpr and run that. just dont expect much

 

yo man if your using the spectre intake piping and cone filter, i would get rid of that, its all plastic, my friend had it and he said he was loosing power cause of it, autozone stuff is as cheaply made as dollar store stuff. head over to no limit in medford, or if u stay at autozone get a K&N cone filter and attach it to the stock piping

 

+1. Mine holds a gallon. Maybe he saved the rest for a custom W/M resorvoir, or possibly to lighten the weight to increase power along with the future RWD conversion

 

Jc61990 where u at on LI? Im at either OldWestbury or Mt.Sinai. Yeah i have a K&N Filter, With Heat sheild...i wouldent trust any other filter. Yeah that 6.5L tank is a little un needed, saves space for possible w/m, weight, and was pondering the install of a Centrifugal Supercharger w/ oil res. in that spot.

 

it says .5L in your sig lol
