I had a bad incident with them the first time I ever dealt with them. I went down there with a couple friends who were picking up parts to get an immobilizer defeat done on a chipped ecu, and to make before and after dyno pulls. Well right after they did it we swapped it back in the car on the dyno and it was in what i thought at the time to be limp mode and we couldnt figure out why. Unfortunately R.A.I really didnt wanna help resolve the issue they just told me they would sell me UNI software for $50 off. After numerous calls to them and after contacting Mike Z from unitronic on his DIRECT line, lol, i found out that it had REVO software after R.A.I. sent him the map and he broke it down. I found later that the ecu defaulted to valet mode. So i borrowed a buddies REVO programmer and boom, fixed. It just left a bad taste in my mouth and I'll probably never go back.
