Sorry if this particular topic was discussed earlier, but I am a machinist and am currently porting my throttle body for my 3.4L grand am. I am cutting the diameter alittle smaller than the typical 62MM aftermarket body. I am getting alot of crap from people at work who work on cars and stuff saying that my computers and sensors are going to go crazy and I will screw everything up. I just need to CNC machine the butterfly in the next day or so. I am looking around the Internet and it doesn't say anything about the sensors messing up with more air flow. Will everything be OK? Anyone care to comment? Thank you.
