at the g8 only show the car was put on the dyno mostly cause I needed air fuel ratio readings. first pull with the cut out opens pulled 343. not to happy but figures the fuel was off. second cut outs closed pulle 363 five min after first pull no tune just closed cut outs. I have my cut outs right after the headers so proved loss of 20 hp. I was very surprised by this
