    Yup, another towing question

    Done! Well I went on my trip and was running the coolant temp at 235 at the peak, and yes I was puckering quite a bit! With the e-fan and under-drive pulleys did give me more oomph going up the hills (cruising at 50-55 mph) BUT, came too close in over heating for my taste. Luckily I don't tow...

    EvoHT programming question

    Here's the scoop, I have a 2003 2wd 4.6 expy and bought the tuner. I put in the efan and underdrive pulley and I do tow a travel trailer (fully loaded around 6K) and I normally put the program to extreme and really didn't notice anything. (I've tried all of the programs and didn't notice any...

    Troyer Performance efan install do's and don't
