After many attempts at altering the msd chip and trying to start my car and failing he got out the car walked upstairs got another chip and proceeded to map my car, now as I'm only a dick head of a kitchen fitter i took that as a failure to alter a msd chip, and then when it wouldnt make anymore boost than the msd map and much head scratching he drilled out the union on the air injector and hey presto booooooooooooooooost, which was prob what was needed for the msd chip to make the power it should of
