no mine is a 2002 HO no smarty just quadzilla iQuad v2 with 125 sac injectors with 61mm hx40 on top and 75 mm s475 on the bottom I overhauled it and put arp rod bolts main studs and head studs and upgraded the valve springs since it has over 60 psi boost mainly did compounds for towing but I can tell it’s been getting a lot better mileage but I haven’t done it on paper yet didn’t get a chance too yet
