Hi all,

I had my car on a rolling road today and it's down on power and the AFR is all over the place.

I was wondering if anyone could give some advice on that the issue could be?

2005 Impreza WRX Prodrive - no other performance modifications other than the PPP.

Was expecting way more than 130BHP at the wheels, since I should be around 260BHP at the flywheel -

and the AFR is all over the place -

Apparently I didn't hit more than 9psi of boost.

Any help would be much appreciated.

Thanks,
Foz

I wouldn't say 10.2 to 10.9 afr when you get going is all over the place, 10.x is pretty normal for a stock map.

Your graph says engine power 130 though now wheel power 130 - that's even worse news

If your only getting 9psi of boost then it could be a problem with the boost control system or the ECU is pulling it back for safety. You'll need to have the car diagnosed by someone to be sure.

Where was that done?

It was a 4 wheel drive rolling road yea as it looks like half the power so may have done half the wheels (Joke)

As said above get it somewhere who can look over it and know what they are talking about as something looks adrift somewhere.

Hi there

Personally I would speak with Neil@Slowboy racing if you are in Kent,he is located just outside Brands Hatch and he should be able to have look on this

And depends on dyno there,we are using only SRR(Surrey Rolling Road) as Charlie there is real legend and he is very helpful

Hope this helps

Thanks,Jura
