Throttle enhancement

I posted and asked about a couple of throttle products and the results came back as this is not a known problem! I have an E450 with the v10 and its like everyone else has pointed out. I do know that the one from hypertech does not fit the unit I have. I forget the brand that there is for the other one. If anyone can tell me would appreciate it. It seems that winnebago has a non standard throttle assy and thats why I couldnt find one to work.

I forgot to add I wrote to the guys at MH magazine and they claimed they never heard of or had a problem so they could not provide any insight to help!
