wow, lots of work in a short time. just curious if those tirese rub. did you reprogram the ecm for the different tire size? how do they affect cruising speed, does it bring the rpm up a bunch at 110 kph?
your truck looks good. lots of cool ideas that you thought of yourself, nice to see that instead of copycat someone else's ideas.

the speedometer show pretty much the real speed compare with the gps speed on the mirror but the thing is the 56 cluster just go to 100k/h ,but that can be calibrated and changed to m/h ,and the small tires take out a little bit of speed but give more hp and torque ,now is very quick and still fast i run at 125k/h by gps at normal rpm the same when gear ratio is changed now have more performance than economy but still economic compared with a classic carburated v8 ,for that im sharing my project ,i start looking for imfo. and i thing is a good idea give ideas about it
