Did you hear that from Bren or anyone else? I can't help but wonder if its TRUE, or justification from them on a protune over a JB4 or whatever plug in etc.
I know a LOT of people around here praise Bren, but they have made some questionable tuning calls on evo x's and that was my last car. Seems to be hit or miss, but either way I already ordered the JB4.
I really don't know if there are issues with meth on the JB4, but I'll look into it. JB4 is definitely what I want to run, so hopefully it is issue free. If not I'll be avoiding meth. A lot of the meth kits have very intelligent failsafe systems too, but I'm pretty far away from adding meth.
