I don't want to cause a war, but I want to know a proven combination to make a somewhat reliable 550 HP daily driver. Obviously I need a clutch, but will I need anymore tranny mods? Sig does not show it, but I do have a BDDL, and gauges. I still have the older extreme load, no crazy larry yet. Stock air box, and straight piped, other than that, it is stock. Is this possible with stock turbo?

 

I have 480hp on stock turbo but will not go above that. BDDL CL/XZT stack

 

lift pump, turbo(at least 62/14, sps or silver would be better), clutch, intake, studs.

 

Its pretty tough to get into the 500's on a stock turbo. It takes alot to break that magical number. I would make sure that you do all the supporting mods first (lift pump, studs, clutch etc) then go for the power. It is a lot more fun when you add lots of power and it dosent break on ya

it was fairly easy for me to make that power just a set of injectors and a smarty and i was at 555 hp, the only thing else that would help would be a clutch i feel i could have done better on an aftermarket clutch. but i know of one other person who did 561 hp with the exact same setup but now pusher pump and he had a clutch. all on stock turbos and cp3s.
