Hi rog, its an NMS chip and yes it was specced to his T34 and 500 cooler the chap i bought it off was upgrading to an L8. Think i will give PJ motorsport a call and book it in for a set uplike you said £100 is a lot cheaper than a rebuild. Just lerarning at the minute its my first cossie. Right then ive just booked it in at PJ motorsport 9.30 tomorrow morning see what they say. cheeRS
