Depends entirely on your mods

Hey guys mods a as follows:

Front mount intercooler

T4 turbo not sure how big its rated at

straight through exhaust

Pod Filter

Dual stage TURBOSMART Boost controller with tornado switch in middle console

Driftf adjustable BOV

Fuel system and injectors stock...

Your car will lose signiicant power if the PFC is tuned for those modifications.

Also running the bigger turbo with stock management is a dangerous proposition unless you baby the car everywhere (dont go WOT or take the revves above about 3.5k) as you risk detonation and engine failure. If you put the stock turbo back on the car would run fine (if a little rich).

Why do you want to remove the PFC?

Thanks heaps guys for the quick repleys and help...

Not sure if im 100% gonna remove the Power fc but my brothers mate offered me $1200 for the computer and hand held controller but i'll probably just leave it the way it is cos i do love my car and dont have the money for any engine rebuild lol

Keep in mind if you can sell the PFC for 1200 and get a stock ecu thrown in you can get toshi (search the traders forum for 'toshi') to remap you standard ECU for around $400 which is a very good option. It will be fine for the mods you have (and as its very hard to detect you wont get defected for it) the only downside is the PFC will be better if you want to do many more power mods in the future (bigger turbo, AFM, injectors, etc).

likely the car will run like a bag of shit with the ATMO BOV.

260rwhp is only 190rwkw, which for a turbo like that is a pretty poor result.

I'd expect closer to 300rwhp at least, and 350rwhp with injectors/AFM

So you wouldnt loose much power right power, would be a bit rougher to drive however as tune could have cleaned it up a bit

I was told that was about the right amount off power for the car as the injectors and fuel setup a still stock...

Also the t4 turbo i have isnt much bigger then the stock turbo, I'm not sure myself im only going on what the previous owner told me.

Its not about right

You can take factory injectors to around 220-230rwkw. Every car is different. I made 220rwkw on stock 25 injectors years ago with a T04e, int gated rear.

If its not visibly much bigger than the factory one, then it probably isnt a T04.

Generally a T04 will come with the .7A/R Garrett Comp cover
