Will I gain any midrange on my car with say... a 2800 vig? Does it make any difference from a highway roll, maybe from 50 mph? Or, is it all bottom end?

 

I am not sure how it will affect your car's mid range with the stock cam but with my Hot Cam it helped it a ton. I gained almost 4mph in the 1/4 mile when I put my 3200 stall in. As far as highway hit's it will depend on where your "Sweet Spot" is. If I am doing like 55 mph & hit it it almost feels like it takes a second to get going. However if I am doing like 45 mph you can really feel it hit & goes like hell. From a dead stop it is simply amazing.
