I've been playing with my PMS for a few months now, it's not too bad to tune with, if you have a basic knowledge of what your after, which is air fuel ratio and where to add and subtract timing.The best move I did was let these guys on here talk me into a LM-1 wideband with the rpm converter, so I can do some datalogging and add fuel where it is needed to get the A/F ratio I'm after. I haven't messed with the timing any yet, waiting to get my procharger kit, which has been 5 weeks since I ordered it, but once that's installed I can tune my A/F ratios and then start adding some timing.Never used any other tuner but the PMS but in my opinion it's easy to use and you don't have to fool with a laptop in the car.
