The JBD dyno that you seen on BMS' site is my car. I was the original tester for the JBD. Same shop did my car with DTUK. Baseline for my car was 245bhp. JBD yielded 308bhp, DTUK Program 3 Map 7 yielded the 365HP.

JBD at 100% and DTUK @ Program 3 Map 7.

[COLOR="Blue"]"Codes that can pop up (and will, generally, with a tune) when this happens fall along the lines of Rail Pressure Plausiblity, but I've also seen Air Mass Sensor and Gas Pressure Sensor. "[/COLOR]

The first one was because I had the clamp to the mass flow sensor lose! after that I did not go SES until a month later and before I did the code erase it turned off by itself. I spoke to my mechanic and he stated that whenever you have tunes sometimes some codes will come up but usually not serious, but he did advise me never to ignore whenever the light comes up.
Limp can come about for various reasons, especially under duress on a dyno (heatsoak, for example). Your RENNtech isn't's one map, whereas JBD at DTUK have multiple options, so while your experiences with the tune are informative and appreciated, it's an apples to oranges comparison.
