It comes with a flash cord and then I can just use oasis or where that program is right?

 

yea you buy a cord with a license on it from UpRev and then you can flash it. You will need a tuner to make the maps. Or you can go piggy back or full standalone like Haltech. You dont need a boost controller. Thats 400-500 you can save.

 

not even close on the suspension, CHEAP "cambergang hella drop" coilovers alone are 1200. For making power might as well stay stock for what good that will do you, what about bushings? better lsd(not needed but helps a ton)? figure closer to 5-6k for a decent suspension. any intention of track? if not then brakes wont matter too much if only highway or drag but if for the track you need those too. guages alone for MECHANICAL guages will run you 300-400 forget about wiring. plugs? gaskets that may be needed? if the kit is 5500 its missing **** or is used and likely needs to be looked over. if your doing all the work yourself figure 10-15k and thats using used parts and catching some deals, 20k if everything new and doing twins(with the singles out there the whole twin thing is a waste really......) built engine for more power?
