forged pistons and rods, Trilogy motorsports blower (which made 250 Marauder kits and are sold out, not making more) 2.8 pulley, fuel pump, boosta pump,injectors, headers, dynotech driveshaft..it's a safe tune, it could be more. I'm considering going to bigger blower, injectors etc.. and go to 550. will need to update trans some for that amount as well.
But there are members on here that have 600, 700 + rwhp, but you need large bank account for that pretty much and or a lot of know how so labor costs are reduced
2004 SB Ported Trilogy 48
