Tested the Blinder M27 on my Benz (has Veil and a Laser Shield) and it was basically JTG on the Tru Speed and LTI LRB. My previous Blinders on the same exact location were giving me 300 to 400' PT's while my ZR4's were........... well I will not go there. It was if I was testing a Blinder on steroids. I also love the ability to customize it to my liking. Programming it was awesome. It is nice to see Blinder step up their game and put their money in making huge improvements. This is their best version yet period.
