i switched to a 454r from TEAM G on my 511CI..but i also had plentum work done ( shortening the two front runners etc..) also had the ports gasket matched etc...very noticable difference in the pedal..can't say how much it picked up the car cause i can't keep the front wheels on the ground without the wheelie bars on car...lol :shock: ....the wheelie bars are now bolted on and ready for next trip.
i would suggest getting the ports gasket matched at minimum as i would suggest with any intake..
