Is the first run bolt on's no tune, then bolt-on's + various pnp'd goodies, followed by the previous + tune?

"Minimal gains" is quite an understatement if I'm reading that right

Just to reiterate my situation, Seymore4 tuned my car two weeks ago in person. Each time he used anything but the stock throttle table, the car almost immediately went into limp mode. He reflashed the ECU multiple times to no avail. So I drove the car for two days in a semi-tuned state (stock throttle table, but tuned fuel and timing). I was able to toggle back and forth between the stock and "tuned" maps, and I honestly could not detect any significant difference. The throttle response was obviously the same.

When informed of this issue, an UpRev rep specifically told Seymore4 that they (on their etunes) do NOT alter the throttle tables for 2013 and newer 370Zs because of the limp mode issue.

The only reason I wanted a tune is to improve the low-RPM throttle response, which would necessarily require changes to the throttle table.

I feel your pain. An EcuTek tune by a competent tuner like Visconti will solve your throttle response problem. The EcuTek tune fixed the throttle hesitation on my 2013z

Your'e exactly right. That's pretty much the same conclusion I have come to after reading all the recent threads.
