Whats your available like over Dec/Jan for mapping? and what sorta price we looking at? Is it done by the hour, or X amount for a mapping session and Y for tweaking later?
It is worthwhile getting larger injectors now, and getting the map done to suit, or just sticking with the greens if im happy around 170-180?
I'd stick with the greens if you're aiming for 170-180bhp, and I think you'll also be able to stick with the stock MAP sensor at that power too. A K03 and turbo cam at 15psi is good for 170-175bhp, so a T25 with GT cam is likely to be in a similar ball park.
We charge £300/day for mapping, and that's plenty of time to get a map done as long as there are no mechnical failures and we start mapping in the morning. I've got no availability during December (I'm away with work at the mo), there might be 1 slot at the end of Jan - but it can be very weather dependant at that time of year!
Best to email our chips address (chips@poloperformanceparts.co.uk) to arrange getting booked in - I've got a few people on a waiting list already for the New Year.
