Hi all I'm new to this forum and have been reading a lot about fitting the TRE Mod and how much more power people are saying they are getting? I have a 2017 M109 and bought one of eBay about 6 mths ago and fitted it but found no difference what so ever to the smoothness or power gain only difference it makes is the gear indicator saying 4th. Is mine a dud ??? or is it in everyone's mind that they have more power now a mod has been done?
