I just put a vmax throttle body on bolted it right on didnt need any tuning..Seems to have better throttle response,runs great.Did a very nice job..Seems like tranny shifts faster now is that common cuz its getting more air?seems to shift all gear by 25 if going slow,what do u guys set ur trannys up for shifting i got the 4speed 4l70!CAN u loose any boost also seems like i lost a pound or so..
