I'm running a t34.48 at the moment, with a -34

I've fitted the greys along side a MSD chip which is for Greys, t34 etc

The car runs fine, by which I mean no excess black smoke etc and idles well.

The only doubt I have is the chip, I checked with stu and he didn't have it on file although the guy I brought it off said is was for greys etc.
