I think that will depend if you want to get it to its 10,000 mile service still in one piece or not.

It runs about 0.9 Bar.

If you turn up the boost without a remap, you will likely **** your engine.

A remap is probably your best bet, you can tune them quite well, but it will invalidate your warranty (all of it, not just the engine).

Std. boost is around 1.2 bar PPP goes to around 1.3 bar but that's with ignition and fuelling re-mapped. Just fiddling with boost is very unwise!

But will your local dealer be able to tell if it has a remap ?
How would they know ?

By interogating (sp??) the ECM the parameters will be different from a standard map

But would they do that on a normal service

Mine has the PPP exhaust on so would they go looking at the ECU ?

No but if something goes wrong they will, tbh i was planning a remap on my scoob when it was weeks old

Its all to do with the risk factor & if your credit card could handle any so called non warranty repairs

IMHO it's got to be worth it, externally it will look like it's got PPP.

PPP would cost me £2k+

Buying the PPP exhaust, pump and TEK3 remap is going to cost me under £1k and I'll have a damn sight more than 305 bhp and If I ever want to whack a bigger turbo on it's £125 ish for a re-remap.

So if anything goes wrong I'll try under warranty, if they find the remap I'll just have to pay and unless the bill is £1k plus I'm still on a winner

If your going down that route mate, just take it to a specialist for servicing, if anything does go wrong then i dare say they wont charge as much as the dealer

Good Luck

Im pretty sure the standard STi runs around 0.9 - 1.0 bar boost and thats what it should have......

I remember when Richard Bulmer mapped mine he stipulated that you should NOT be turning the boost up and it still runs 0.9-1.0 bar. I may have got this wrong though, like I do most things.

The paek figure you get on a gauge with a telltale will not be the same as either the target boost or the true figure it holds. Depending on when the throttle is opened (engine speed wise) has a big effect on how much it overshoots the target. It would be entirely possible to have a std car that overshoots to 1.4bar for a fraction of a second but holds 1.1bar in the midrange where a remapped car has no overshoot and eventually holds 1.3bar.
