School me - V10 Performance Parts
Depends on your driving style. If there are dents in the backside of your radiator, from your toenails constantly running into it, probably not much. 
I would imagine gearing plays a roll in there as well. If you have tall gears in the rear (lower, numerically) probably even less, with deeper gears, likely gives you a wider margin. (tire size figures in to this as well....) I run 33's, with 4.56 gears. The truck will literally push the house of the foundation, without much effort, but, don't try and tow a trailer at freeway speeds........ I can literally WATCH the gas gauge go down. (and gas mileage DIVES DEEP into the single digits......)

I forgot about gearing it. That as good a mod as any.Driving habit is kind of where I thought most of it would be too.

Throttle body spacer does absolutely nothing on a port fuel injected motor. (aside from lighten your wallet.)
There are a fair few folks that do tuners for the V-10, I think Hemifever does, there is also a company in Livonia, (which I can't recall their name just off hand....) that will do tunes as well. As for the hardware, Jegs, or Summit have what you are looking for.
Whereabouts in Michigan?

How many miles on it?
I would start with a compression test and if that's good, start running a lot of fuel injector cleaner through it. I had power issues when I bought mine even after major tune up. The injectors were a mess.

My son-in-law does concrete.
He seems to go thru trucks like water. (beer?)
So far, I haven't had any sensor issues. (knock wood.....) Hoping that I don't. Would be interested to hear how the aftermarket fellers work.

I have the first one made. Can't really tell you how well it works as I did a cam at the same time and have had issues with that. Seems to be of good quality thus far though. Just note you need to send him an upper intake to cnc out to match the much larger opening.
