Yeah it is. It mostly happend when its on an incline.

its certainly likely that its a case of hitting some cells that have too much ignition timing. the faq shows you how to make sure that is the case, then offers advice on how to fix those cells or you can take it to your tuner. if you take it to your tuner you should inform him of rpm, engine load, and if possible a spot where it is on the map tracer, this will help them debug it much quicker and fix it.

dont go the braindead dial the cas back to fix it, like some tuners do
