i have a riffraff billet wheel ordered and in the mail as we speak.
another guy commented on the riffraff wheel which led me to purchase it. just search for it and you will find it.
he claimed 1-1.5 mpg increase, gained about 5 lbs of boost, little lower egt,
and of course more power.
im sure the 12 hp increase and 40 tq is accurate.
ive bought from riffraff before and their stuff is top notch.
ill comment when i get my billet wheel installed
im hoping to max out my 35 psi boost gauge. and of course gain some mpgs, if i can keep my foot out of it.
the hp numbers advertised by no limit tuning are most likely for a 99-03 7.3 not an OBS 7.3
