What is the difference in them? I see an LM1 and an LSU 4.2. HUGE price difference. why? I kinda want to go for the one that is only 80 bucks, but is it crap?
I will be tuning for nitrous (with some help at first from some experienced HPT users). so I would like to know the accurate A/F. Will the cheapie cover it?
