i have stock engine, stock twins, pf intercooler, catback exhaust and ecu how much could i make the ecu also has low med and high boost.

 

which ecu? if aftrrmarket the stock fuel system is good to about 14 psi. that would get you around 300whp but might want to upgrade cooling also, at the very least ic and radiator. the twins aren't good for much more than that.

 

see you have upgraded ic already, missed that. still stands about the same though, you can push the twins a little higher but not recommended.

 

here you go, not typical but it can be done.
10.8 sec quarter mile on stock twins.
411hp @ 18psi

If it's the pfs ecu, trash it.

 

While yes on the stock turbos nearly everything else was upgraded. The OP is on stock internals, stock port, stock injectors, etc. I wish it were that simple but it isn't, above 14psi your injectors have trouble keeping up, if you run out of fuel, boom!

 

I have just about the same setup and I'm pushing about 307 to the wheels at 13 psi. I'm at about 90 % injector duty at WOT, time for upgraded fuel system.

 

A little reseach will tell you around 300whp. The stock fuel system isn't adequate for much more, no matter what turbo's, exhaust or ECU you have.

You should try searching before posting please.....

 

yes its the PF ecu. it also has a bigger radiator idk which but its prob PF since every thing else is PF.
