Hi guys, i just had a 10k service and they put a updated tune in ,now i have lots of popping on overrun which i can live with as it upsets the locals...i do have a Very bad miss fire if i gun it ? I returned it to the dealer and they told me it had spat out the tune so they cleared it and reloaded the update again..three trips and the missfire is back
......Has anybody had the upgrade put in and do they have the same problems.
They told me a sprint owner had an upgrade put in and he hated it
