plug and play all the way 100000000% best mod i have done for my set up made it really mental! yea may cost 500+ but it take 10mins to plug in and your away (installing take good 60+ miles or so for it to fully adjust thow) so means no fanny on getting it mapped! also been there and was a piss take try get the jam ecu defo the mean green fighting machine like.... obv you kno it does this.. Raised Rev limit 8krpm Removes the 180kmph speed limiter Its self mapping/learning for fueling to a certain degree,which can allow it to run 1bar with no other fuelig mods. More agressive map which usally results in more tourque and power. Its a plug and play unit. Factory "jam service" seals still sealed, adjusting ecu to deal with your mods.
