Around 12lb should see your power figure, I'd be expecting 330rwkw(ish) on 15lb. Are you tuning it yourself or using the HPT gear purely as a remote interface for your tuner?

If you're tuning it yourself jump on the HPT forum as well.

Hi Ralph,

I'm the Tim that did the tuning.

I do agree it's a bit short for that boost level. From memory it made 298kW at 12PSI. We had just raised the boost which made the 309 before running out of time. At that boost I could also heard audible signs of valve float up top, hence dropping it back.

Hoping to sort out some new valve springs, go back and add some timing to that load level. This has been a big education for both of us so we're happy with baby steps and learn along the way.

I'm on the HPT forums as well, they've been very helpful throughout out the journey.

Thanks for your feedback

It is being tuned by my mate as a first time tuning sort of thing. So basically a home tune job using HPT, learning along the way. I am the lucky guinea pig :) there is no professional tuner involved..

Big thanks to Tim for his hard work too!

What do you think about the BOV? I've heard of guys running lots more power than me on a stock bov and that it should be fairly quiet?

My username over on the hpt forum is Hiddeous,i do recall you posting.

I didn't realise it had stock springs power to boost level makes sense then. Get some springs in it stat!

I see what you are getting at there, so I should sort of double my power if I push say 25psi through/past those springs while compressed? :P

I am very keen for the springs, they are pretty cheap too - but the tool to fit them while in car is the expensive bit!
