If you want faster acceleration you will loose more gas than before at the same acceleration.. Now you peak acceleration will be slower but when you are cruising you will be using less gas for sure, plus you not have a higher top speed as well, who knows by how much yet though.. I dont have any local roads to test out top speed on haha..The +1 gear will def get better fuel mileage.
If your lowering the rpm, the engines not moving as fast, therefore not using as many combustion cycles.
less combustion cycles means less gas used.
however if your engine is working harder, then it will also use more fuel, but this setup by the reviews does nto seem to hurt take off or overall power at all, so acceleration should remain about the same amount of gas used if not a little less.
I dont know what anyone is saying, I am so tired this morning haharight, thats what i was saying lol
