Hi I was getting dyno tuned by Watson Racing in Michigan and after they were done checking over the tune in asked if I could have a tune for dyno days. I wanted to run the car to 6k instead of stock Rev limiter which is 5500 I just wanted a few more hp right now it makes 301 and 305 tq to the wheels. but when they went for the 6k pull it started loosing power right after 5500 rpm is this because of my waistgate maybe opening because I think it has a 8psi spring or is the pulley "maxed out " look fwd to hearing what you guys have to say.
