    Crap, that's what I was afraid of. A reflash is about $100 (had to do it once before on a different vehicle).

    Yeah, that's what went out in Feb. 4th gear clutch shaft finally pooped after about a year and a half of showing problem signs (I tried to milk it for all I could before it finally went). They showed me the clutch shaft and all the splines were worn completely smooth. They replaced it with a hardened clutch shaft.

    So if a reflash has to be done, should I just go have it reflashed at the dealership and then have it reflashed with the DHP tune? I'm really unsure of how the programming works and if there is even a point to having the dealer flash it if I'm just going to put the DHP tune on it again. I don't know if anything the dealer does will remain if a DHP tune is done afterward, does that make sense? I'm kinda lost on what to do next. I suppose I could demod the car and wouldn't have to worry about it, but that would suck when I've had my mods for over a year now and they've not given me an ounce of trouble.

    P.S. FoSho, your car is impressive. Props.
