I just wish $600 included being able to switch back to stock, then it wouldn't be that bad imo. I know its become popular to hate on APR lately, but they deserve credit for being the first to get port tuning out for us (which pushed other tuners to do the same), plus they are currently working on a new Stage 1 file as well, which is pretty cool considering other tuners have stopped doing anything new long time ago.
to be fair it costs similar money from giac to be able to switch programs to stock.
I would be much more ok with their pricing if they still had the same fee for going straight to stage 2. not a $150 penalty for not buying their $800 downpipe.
