After reading all the relevant tuning threads and conducting my own research, I decided to get an UpRev tune. My car is not heavily modified; I was more interested in increasing the throttle response than maximizing power.

This past week Seymore4 street tuned my car with UpRev. First of all, I just want to say that if you are interested in getting a tune and you are not near a dyno tuner or not interested in having a dyno tune, then I suggest you contact him. He is excellent at tuning, extremely knowledgeable, very friendly, reliable, prompt, and fair. He is active on other forums as well, where he has a great reputation and is held in high esteem.

So with a couple of second- and third-gear pulls, Seymore4 was able to tune the timing and fuel tables just fine, but when he would alter the throttle table, the car would almost immediately throw a code and go into limp mode. He tried starting over and reflashing a couple of times, and the only time the car would drive normally was when the stock throttle table was retained. My car's ECU part number is listed in UpRev's database, so it is a known entity. With just the timing and fuel optimized, there was almost no noticeable difference in feel from stock on my particular car. I toggled back and forth from the stock map to the tuned (timing and fuel only) map quite a few times to see if I could discern any significant difference, and I really couldn't. I think the throttle tuning is vitally important when tuning our cars.

Seymore4 contacted UpRev about not being able to tune the throttle table, and they responded that they have had experiences similar to mine and thus they do not alter the throttle table for 2013 and newer 370Zs. Maybe my knowledge base is lacking, but what good is a tune if the throttle table cannot be tuned? I wonder what would have happened if I bought the tune from UpRev directly. Would they have allowed me to return this product if I reported that the car felt no different from stock? Would they have warned me ahead of time of this issue based on the model year of my car?

Anyway, Seymore4 is a man of his word. He removed UpRev from my car and gave me a full refund.

Does anybody have any other input regarding this issue? Surely someone else with a 2013+ 370Z has an UpRev tune. I can't be the first one to experience this.
