Twister, Redline, White Knuckle, and several other VERY knowledgeable shops are within the area. Ive dealt with power for years, they are 3 miles from me. First, they are fucking CLUELESS with banshees. Second, they WILL CHARGE you if they "think" they have a fix for it. Ive got a hard time thinking that you paid ANY knowledgeable person 200 dollars to come look at your junk that wasn't able to fix it.You have a BONE STOCK SETUP with pipes and a filter! These things are as simple as they come.If this "super dupper knows it all guy" couldn't figure it out in just a very few minutes you need to re-evaluate your perception of his or her knowledge. And who takes payment without fixing the problem? Also, Ive got a hard time thinking that Sean put your junk on a dyno to jet it with such a basic setup. Hes literally setup hundreds of this same setup Im sure. I doubt seriously he needs a dyno to jet it! You sir, are going about this in a very wrong way. Dealerships are for acquiring OEM parts and that is all. Either take it back to Sean and have him fix it, or take it to one of the others Ive listed. Hell, even Dave has a really good chance of doing it for you, and while it wont cost you cash, he might require a sexual favor for his time.
