When I first broke my engine in, I had it tuned well. I have noticed that lately the acceleration has been a little sluggish, but the temps have been around 70 degrees (vs 90 degrees when i first tuned it). I'm assuming that ambient temperature has an effect on the tune of the engine, but I'm unsure of whether humidity also has an effect. If I'm correct, what is the best adjustment to make when the temp and humidity change, or do I have to start from scratch?
 
its best to start from a factory tune , when you are new at tuning. but once you figure out what your engine likes for certain temps it gets easier. temp humidity and altitude will all effect the tune of the engine.
