Same here I am using the R32 throttle body and the difference in response is very small, it also got a bit more sensible on maf readings I have had a couple o cel with a correlation code. The real benefit on the one listed would be that it has a metal plate, when using meth and higher boost levels the plastic gets brittle and snaps in half.nothing proven on my end but i did notice better throttle response especially with the bigger intake manifold. no tuning changes. looking for thread
