none. I am running a stock A9P with a Diablo chip tuned by Thunder Autosports. Car idles around 900 rpm. It does idle a tad rich but the smell comes from the lack of cats more than the tune I'd say.
I will be needing help with the Mspnp2 for sure, its been a slow build but Im looking forward to driving it soon. Im working on wiring up the wide band this evening, still don't have a boost gauge, do I need a fuel pressure gauge?
