    It should get close.

    I didn't believe it was possible on the 25r myself until I looked at the screen and saw it, I was expecting around 235/240

    It would be a lot better to get a group of puntos on there then its better to compare set ups etc.

    Definetly a good turbo is the 25r, i should have water/meth installed on mine too

    Pete also why did you choose such big injectors mate?

    I'm using a none rising rate regulator and I was maxing out my 330's, I wanted to make sure I wouldn't need to upgrade them any more so I went to 440cc

    Stunning results for that boost and self-mapping Pete. Do you still offer refuge to homeless pistons?

    Not often but I do have one I got for 3.65 (postage price) in there. Not enough torque on the arps let the gasket move, the overheating if the head due to water loss caused detonation in one cylinder and the ring lands to be damaged. Went back to standard head bolts after it happened again, pistons all survived the second time.

    I would like to ask about BLUE Run No1
    Why did it put more HP and why did you stopped it early ?
    Looked like it was going to make more HP !

    If you look at the afr graph you can see why, between 6 and 7000rpm it was running leaner, the next run had more fuel and made less power.
