SOUTHERN SMOKE· GA CUMMINS CREW PREZ & Captain of the USS FAILBOAT
id suggest studs, and stiffer rods also running 4k, thats alot on the cummins. there is a reason they defuel at 3250 stock from cummins. :thumbsup:I'd imagine Marco is working on it for the smarty, its just a matter of time until they come out with it in the form of TNT-R software. You'll need upgraded valve springs when it does get here.
