i bought a ihi vf23 n don't know which ecu should i use!!! i wanna to make 300-350 whp but if i using stock injectors and stage 2 ecu can i still get 280whp?? does it hurt the engine?? well bc i am trying to use less money to keep my wrx run fine but does not have to run very fast.

here is my qustion do i have to have sti injectors, pump, fmic and dyon tuning?? can i just keep what ever i have n install injrctors............. stuff later??? also how many boost should i set for this and with all the good stuff??? if i need to tune, is it a good idea to tune on my turbo sx unichip piggy play?? or need new computer, like utec, cobb, ecutek, ........ which oone is good ??

I have a Cobb AccessPORT and I'm very happy with it. I believe there is also a program where you can tune your own car with the AccessPORT. I can't remember what it's called though. Sorry....

Accessport allows you to tune your own car so im confused what sinister means. But yea your gunna need new injectors and fuel pump if your even considering going over 250hp on a wrx motor. If you want a reliable 300+whp motor check out a Cobb Short block otherwise your engine wont last much more than a week or so(unless you run VERY low boost) which wouldnt make much sense. Do your engine a favor by strengthening the internals and block before you even think of making that much power! p.s lose the bov if u still have your stock bypass valve put that back in.

vf23 already installed for about 1 month runing good with stock injectors n turbo sx stage 2 unichip. it run smoother then stock turbo, i am saying this bc b4 it had a cel reading maf high output now is gone after i installed vf23 and alot smoother. i was runing 16 psi on stock turbo , now 12-13 psi . i am waiting for pink injectors n utec. well i think 300whp it safe for stock block bc my friend has vf39 nfor a year pulling 300whp with no problem i am not sure how many psi he is running but sure. well i hope after all the stuff i get ( ex. fmic, injectors, ecu, tuning.....) can run 12's n 300 whp even 280whp i am happy with it!

300whp with stock internals? i dont see that being very reliable. Maybe 300BHP...maybe, but you need forged internals to safely handle all that power. im pretty sure hes talking about a wrx not STI but if not then im wrong.

yes i am talking about wrx n my friend who has vf39 pulling 300whp dyon tune by top speed 12's sec 1/4 has notthing worng with it, the only he need is a new clutch!!! he has it for about a year. well i think that is the prove! maybe it not safe for long trem ( 5 years n up ??) anyway 5 years later wrx engine going to be very cheap..... n by then surbaru going have some thing more then 350hp......
