my local mpg blow. most every one else does 18 to 22 local. i see 14 all the time. i just did a PE tune a while back, ive gained 1 single mpg local lol

so your mpg blow so yours must be supercharged and that tune should help also

No. A cheaper way to clean out the engine is to add in a quart of trans fluid.
