UpRev w/Shawn Church (Church Automotive)

state

My Z spent a few hours at Shawn's place in Wilmington yesterday, 9/1. It's only my second time there, but I can tell you they know their cars! Shawn has a VQ37VHR (G37) and my base tune really benefited from his extensive tuning experience on his car.

While there, I saw a number of interesting street and track cars. One EVO was tuned for E85. Very interesting! His website lists an impressive array of cars for which they have expertise.

So, we started with his base tune. It turns out we have similar mods, but the Z exhaust is bit less restrictive. It's also unclear what is different with my particular car/ECU (I hear upwards of 10 ECU variants per MY, and you have to figure they are different for a reason!).

Bottom line? My 2013 370Z with Motordyne's ART pipe and tune makes 345/280 to the wheels. I can't say whether this is typical or not, but Shawn believes this is the most he's seen for this state of tune.

Here are a couple graphs to illustrate the before/after (it's worth noting that it's not a true baseline -- I had the ART pipes already installed). Also note the AFR. It seems our cars like it a bit richer than I'd think! It runs a near steady 12.5.

I'm happy with the results and I'm curious about other recent results (especially AFR).
