How many guys out there have the LT4 hot cam and have noticed terrible gas mileage from your car? My 97 TA WS6 with 4.10's gets maybe 200 miles out of a tank with highway driving.........thats horrible, especially since it only have 25K original miles and maybe 1500 on the new cam,etc. Also, do you think with a 52 MM throttle body I will see any performance or MPG increase?

yeah, had the computer re-tuned by Ed Wright for the modifications it currently has. The thing is that it definitely is running super rich because there is so much soot on the tailpipes after a short run and you can smell it also when running.........car runs strong though, so not sure if there is a problem there or not.......Comment
