So I have the three setting tow street and performance (or whatever they are called). It seems like the highest setting is no faster or more putting more HP out to the wheels as the middle setting (the only difference I notice is more smoke). Is this a common thing? I have Sinister DPF delete and EGR deleted as well. Stock exhaust pipe

I think the hp difference between the two is 50 - 75 hp. Not a lot. The biggest problem is not keeping up with the fuel demands that it requires
