I talked to APR today, and I wanted to see if I could confirm what they told me...

my mechanic installed a simple MBC in parallel with the N75 from the outset, but it only worked for a little while before the ECU called BS on the whole thing.
the GIAC chip has run with no overt problems, however it's not nearly as smooth as the APR software was.
i'm still playing with GIAC - my CF's are high and my knock voltages are also high. audible pinging sometimes. going to try some new sparkplugs to see if that helps.
based on all that, i'd recommend one of the other options out there. not that GIAC's *bad*, but i think it could be better.
