But only in 2nd gear?

That's right at 3000 rpm.

1st gear 24 mph
2nd gear 37 mph
3rd gear 50 mph. at 3000 rpm on the v2k. Try 1st,2nd and 3rd gears at these speeds with the same roll on throttle acceleration as you would to try and duplicate the problem that occurs in 2nd gear, in 1st and 3rd also.

Find out if it does it when the engine is cold also or only once it's warmed up. It doesn't sound like an ignition misfire if it's only happening in second gear and only at the certain speed. Possibly a problem with the ECU or maybe the fuel controller if he has one. I'm not talking from experience now so bare with me. I'm reading into ideas from another thread / another forum. Says to disconnect the aftermarket fuel controller, if he has one, and see if the problem goes away or changes. You could try this for starters.
