[QUOTE="nosympathy, post: 13666892, member: 151682"] So, I have a question concerning the Boss engine making power. Had the car dyno'd today, and the numbers were ehhh. I told them to run the car to redline at 7500 but they kept running it to about 7200 and wouldn't run it any higher. Think it is because they are a dumbass chevy speed shop and they don't know what anything above the redline in their camaros looks like. Since the graph shows, as I have always seen and read that the boss engine doesn't peak power past 6600-6800 but continues to make power, would my 373rwhp dyno pull have made it into the 380s with that extra 300RPM they wouldnt pull? The car was still pulling at 7200 in a pretty steady upward line. AFR was all over the damn place though. Dipping down to 12 and back up to 13 repeatedly. Just wondering what was "missed" in a sense. Kinda pissed me off when a few stock 5.0s were dynoing the same hitting the speed governor as I was dynoing at 7200. With one running right after me and putting down 371rwhp stock tune with a tuneless CAI and only making it to around 6200 before hitting the speed governor. **EDIT** Not sure if they did it to me on purpose and not to others or what, but after watching the video I took, they definitely ran my car in 4th gear. I think I was freezing and annoyed so I didn't catch it. Also their dyno was making a god awful screetching sound that was louder than my car. So...might explain a lot, don't know. Will be the last time my car sees this shop again for a dyno run. I'll drive over to Finish Line and shake hands with Beefcake and beg him to let me have my car run on their dyno before I'll take it to this place again. They ran my GT in 4th a few times on me a few months back. Waste of $40. [/QUOTE]
