the tuner should have his own a/r sniffer. redline should be in the low 8's imo. I make 400rwhp on a mustang dyno and 450rwhp on a dynoject at 14psi. GT42 and monster streetport, it does help spool with that huge port.

But what kinda of chances I'm taking if boosting at a level like this? Don't think stock rotor tips or seals will last for long on 25psi!!!

If you want to run 450whp, you're going to have to either run higher boost (~20psi on that turbo) or a much much larger turbo at a medium level of boost.

Stock 2mm 2piece seals should stand up well at 450whp so long as the tune is good.

Not greatly familiar with the PFC, but as far as fuel and IGN tuning, you're not. You just have a smaller view of the map on the controller then you would on the laptop, but as far as which options are accessible through it and which aren't (be it corrections etc) I'm not sure.

The compression numbers aren't terrible, but they're not super healthy either, front rotor is a little low.

The exhaust may be a factor holding back the power if there's some 2.5" sections in there.

Your issue sounds like multiple little ones as opposed to it being oen specific problem. Make the engine run more effciently in every way concievable and you'll hit your goal..............using that turbo :)

And he will probably tell u where the bottleneck is. It might be the tune, it might be something else. I do belive pip takes about 350£ for a full tune. And he has a dynapac wheel hub dyno.

So give em a call. Think he got betweeen 1-2 weeks wait on tuning atm.

I know WGT, they are only 25 minutes drive from me, but my experience with them in the past proved expensive. When I had the stock twins I went in for some boost issues and had the cultch changed at the same time, bill was just over £750 ...

I was having second thoughts of calling Pip and see what's the situation is like so might do that.

And it does take a few hours to change the clutch. And it def takes awhile to troubelshoot twin boost problems if the problem is not obvious.

So id try Pip once more if i where u. He will ofc charge u for trouble shooting things.

Take the car to him, if he's only 25 min away. Explain what's going on and i guess he will get u sorted. Oh and don't run the car on 95. Tune it on 98 and then use 99 V Power
