Personally I would just get it tuned at a shop with hpt, it seems to be a little cheaper but good luck with the gms1

how long did it take you guys to install it? I plan on installing the wires myself and then having the dealership flash it or whatever. So how long was the installing part and the flashing part so I know what to expect when I put it on next week.

Thanks

About two hours using the pigtails, soldering & heat shrinking them on instead of using the butt splices.

Don't know about the flash. They'll prob charge you an hour at least.
