I took my plane in yesterday to get the engine tuned. And they said to call today. So i called and they needed fuel to tune my engine which was messed up int he first place. And with fuel 20 bucks a gallon thats kinda expensive for me when they have gallons of it. They also accused me of taking my engine in because it needed tuning after i took it off. I said no, It didn't work well so i took it off. The gu also asked why i was using 15%. By now i was getting pretty fed up, So I told him one of you brilliant coworkers told me to. BTW my next plane or gear by will not be from them. I plan neevr to go back after i get the engine tuned. Since i have gotten my plane there, all these guys have been is jerks. I am seriously thinking about leaving some feedback.
