I have built hundreds of 12 valve trucks for towing his issue is not rocket science. My builds are capable of towing large loads over the Cajon,and grapevine and any where else they want to travel. I am well aware of the factors involved. No a plate is not the only way to control egts-he has the wrong one for towing,that simpleAre you telling me that a fuel plate is the ONLY way to lower the egts? You have not taken rpm into consideration like quoted above. You have not asked about tire size or gear ratio. We are all trying to help the man, but just telling him to throw in a smaller plate is not giving him all the facts. I would be looking for a solution that allowed me to keep the power and lower egts. I usually agree with your advise, but is sound like you are saying this is an impossible feat. It is not.
