Power expectations after mapping..
 

Any advice on what sort of power I would expect after mapping??
I have a V5 STI,just got 255l fuel pump & 550cc injectors,it already has a newage TMIC.

I am thinking of a TD05,but want to see how this goes first..
Any advice guys..

You haven't mentioned what turbo/exhaust its running mate,but my v5 sti wagon was running a vf28 and had most of your mods but mine had 440 injectors and made 312bhp but mine also had a full 3" de cat exhaust and k/n induction
Upgraded a lot mine and forged engine ,fmic etc etc and now running a TD05-18g with 375/353

Sorry,I ment to say all else is standard apart from 2 1/2" system all th way through,with equal length headers. Standard turbo etc.

My V4 with vf28 and same mods as yours but standard top mount mapped by JGM on Area 52 rollers made 300/300.

Cheers guys,think I will just go for a bigger turbo before putting th bits on and mapping,I actually thaught th vf28 would pull slightly more than that with supporting mods,good show tho.
Cheers Paul & noise

VF28 is capable of 330 bhp on good fuel with decent supporting mods

cheers

To add 440cc injectors will do 340 something with a decent fuel pump fitted on std fuel pressure

cheers

Cheers for th info Bob,much appreciated.
I'm in two minds on if I'm going to up her in power or stick her away in a garage,and start a fresh on a blob. I know it's going to be an endless money pit if I go ahead with th V5. It's th handling of th V5 that I just can't see past tho.

Thanks again
Cheers
