I actally prefer the 1512 to the 1515. I had a 1515/2.5D and traded it to get another 1512/2.5D. The 1512 is MORE than enough power for any truck except for maybee the absolute heaviest. Even at 13 lbs you will still be turning your epa down.

Compared to a xl motor it will run tons cooler and have just as much power, probably more.

IMO would 1512 will make you very happy, especially if you like a snappy feel like me.
