i was curious what is the most whp gains anyone has seen on the dyno and with what set up? i want to start doing engine mods and what to see what up

The most I've seen posted is in the range of 15-20 whp with Stillen Gen 3 or Injen long tubes. I personally don't think it's worth it. Save the $$ and go SC or TT

i know best bet is tt or sc but i was wondering what kind of whp gains from like cai headers hfc exaust and like uprev tune

ask G37 sam about this he has some good gains with his set up and tune.

I just had my G tuned at HB speed 321whp 258t

Do the basics; cold air intake, high flow cats / test pipes, catback exhaust, tune.

screew the teest pipes and get fastintentins LTH's

... or you could do that too lmao

i would be happy (at least thats what i tell myself) if i could push out high 300's whp. but is this possible with basics i know the tt and sc will get way more than this but if i can just get cai, fi lth's, exhaust, and what ever else without going tt or sc route i would be happy in the high 300's

Not gonna happen with those mods but you'll at least feel the difference from stock. So that should hold you over for a while.

I got 402whp 380 tq with a 100 shot.

im still up in the air on buyin the lease. if i buy it i want to do it right from the start. not waste money on intakes or anything else that would be replaced with sc

Start with a car thats aleady got a FI setup. Like 335 for example. ECU upgrade yields 30 - 60hp right off the bat.

By the time you drop the money into making this a realllly really fast car you could have purchased or leased something way faster in stock form to begin with.

Otherwise, Intakes, HFC, Exhaust, Tune, Flywheel and Clutch is your best bet.. and I wouldn't even do that to the car. I'd stick to Intakes Flywheel/Clutch setup.

Just my opinion.
