Tbh you might as well go for the finsport upgrade if you want the open filter.

What does the finsport upgrade include? sorry for all the questions and thanks for replying!

Stage 1 is Induction & Remap i think, Then stage 2 includes the exhaust and different map. Everyone that has dealt with him havnt had a bad word to say, the power seems really good too

Just had a look, stage 1 is just the remap and all cars have been between 215/220 which is £395. Stage 2 should be induction, exhaust etc around 230hp.

Cheers thank you will have to have a look into them thanks for the info and research !

What do you mean by Dump Valve?

Here in NZ a dump pipe is referred to as being when you cut the internal wastegate pipe off to dump below the car as opposed to reentering the exhaust after bypassing the turbo.

A dump valve is therefor an external wastegate plumbed to do the same thing?

Dump Valve is the thing that goes psssst chhhhh when you let off the throttle
I think we call a dump pipe a screamer pipe

A dump valve releases the pressure in a Turbo'd engine

Ohh so you mean a blow off valve... Mounts to the turbo- intake pipe... If your after just a sound over performance as stated, run a pod with no valve and you will get compressor surge like a rally car... Rally cars don't run BOVs because they run antilag.

If you want performance run a valve because otherwise the excess pressure in the intake pipe when the throttle body butterfly closes when your off the gas slows the compressor wheel on the turbo and increases lag/ spool time when your back on the gas...

A valve will also cause the car to run little more rich, but wont your guys emissions laws make a atmosphere venting valve illegal?
