Arent you paying alot for the name?
Plus dont the emb and ultimates have alot more tuning points, thus having a more efficient map? and have a better result on the rollers and on the road
agreed, the only plus side is that these will never really drop in value....
for an emb - £350 for the ecu and wires
then say £250 for fitting and mapping - ultimate costs another £150 to buy it.
so when you come to sell it, your only going to get a lesser percentage back on what you paid for the ecu, the mapping you have lost out on.
Plus any mods that are addedd, your effectivly going to need a remap, where as the blitz and other ecus dont, its just plug and play.
Yes you should get better results with a piggyback...however what these translate too in performance...dont think anyone has done a test have they?
