Does the whisper tune wash lube from the cylinders, damage injectors, high fuel consumption, any side effects at all? Extended idling periods are probably not the best thing in the world when idling quietly, but the couple of minutes most people spend in drive-through windows won't hurt anything.I realize that it won't whisper until fully warmed. Is there an additional cost to adding whisper to all my driver tunes? No.

2) Is the 65 HP tow tune (7500-10,000#) the proper tune to get for high reliability towing my 8000# RV trailer? You can use it (as that's what the website says).or should I get a conservative 40 HP tune? Do the tow tunes cause EGT problems? This is the #1 reason that different power levels are available. Higher horsepower levels at sustained high load will experience higher EGT.
