Hi guys
I think my head has been skimmed a bit over eagerly. Any solutions? The guy at dastek also rekons so cause if you boost more than .7bar the car starts to detonate.

I dit do a comp test and its a bit lower than the manual say, but they are all the same. Dont trust the gauge that much thou.

If your compression is lower than the manual I would not say that is your problem....I suspect it is a bit lower than the manuel says....so even if the guage is not on the dot it is not a big factor.

I actually have the same problem, comp readings are way low, but even on all cylinders.
havent tried another gauge yet though and i did it with a cold engine wich affects results. I 1st need to sort my radiator problem and then il move onto that
