40hp-210hp tunes have similar shifting to stock, but slightly firmer. The 40hp-175hp tunes cycle the EGR all the time like stock, but the 210, 210 tow, and 250 tunes only cycle the valve at idle and keep it closed while the truck is being driven. The 210 tow, 275, 300, and 310 tunes have much firmer shifting than stock and also have early lock-up at 38-45 mph (depending on gear ratio). The 250 tune has a stock shift pattern, but has much firmer than stock shifts. The 275, 300, and 310 tunes have the EGR shut off all the time.
My two favorite daily driver tunes are the 210 regular and 300 tune. My favorite highway tunes are the 300 and 310. The 210 tow was designed for heavy towing. Light towing can be done with the 210 regular and even the 250 tune. Some even tow with the 275 and 310 tunes (we do not recommend this though).
