MG ZR: Cams & Maps

[lolsteve]

My blue one was 140 when I got it rolled, think she was a bit poorly back then. This mk2 is getting rollled tomorrow with the stock manifold to do a before/after test to see if the mapping makes a difference/check not running too rich or lean etc

Think theres been some testing on the decat effects on ZRs too and the consensus is it's not worthwhile
