im sure the blits access computer is just a hacked standard computer, with all SPEED CUTS, andREV limits takin away...
its still a closed loop computer.. so it WONT HURT IT.
to be honest, resetting the stock computer after mods is a good thing for sure, BUT it is still got only a small band of tune.. like if you getting a full exhaust a pod, front mount, and winding more boost into it will still only be able to tune to its best ability, and its not that good.
and then again, getting Power FCs or full on aftermarkit computers cost ALOT..
So i spose it can be only a good thing to get a better tune via a quick reset.
