added this to the quig today...Bullydog Watchdog
picked this up on craigslist for $150! I haven't really tried it out but it moniters the rpm, intake temp, coolant temp, speed, fuel econ and more. also got to test out the 4x4 in the snow today.. works great, just need more aggressive tires. surprisingly you can only fit 275/55/20 on this thing and they still rub so Im thinking of going to 275/45/20 so I don't have to worry about any rubbing... and also added new headlights!!! they are bright now!
