what to do before a remap!
 

done a power run on my p1 last weekend, it made just over 290 bhp, 250 torque!
i've no cats in it, and a vf35 turbo! the man says he could get it a bit higher with a map
appart from them two items the car is standard, what should i do before the remap, should i get a boost controller, or any other bits to help with the map!
thanks, Mem
