Just stacked the Smarty with a Diesel Dynamics True Torque Power Module. What a difference! Talk about get up and go! I went with the #8 setting on the Smarty and let the TTPM take care of the timing. I went with the TTPM as it has less timing which seems to work better with the HO engine. I set duration for 5 and torque for 6. I've never seen so much smoke coming from my 4" exhaust! What a product! I was able to recalibrate my speedo and odo, too. I set top speed for a conservative 130 mph! This is an excellent, well engineered product. My hat's off to Mads! Anyone else running this combo?
