If you can stretch to it why not get your car livemapped once its all sorted. I went the extra step when I done mine very similar to yours. Im not saying chips are bad, but you cannot beat a tailored setup. Your safe in the knowledge then.

Mine is a t35.55, siemens 55's, l8, 500 cooler and everything else that goes with. Got mine live mapped and its now a fantastic road car thats plenty quick.
