Message	Well, as most of you know my dyno tests have been showing increases each time. I've been reclaiming lost HP through a lot of time, troubleshooting, and hard work. Oh yeah, also lots and lots of money. Well, today I got it done again hoping to see some good numbers. On my last dyno I pulled 288 RWHP. I found out I was only running 11 psi though. I dyno'd again today but this time I was running 13.5 psi and I gutted my main cats. I only managed to pull 274 RWHP. The numbers shown are not the actual high numbers. I lost 14 RWHP AFTER gutting my main cats AND reclaiming 2.5 psi. What went wrong here? They told me my shifting was smoother and overall the car drives better even though I lost some numbers. It accelerates way faster now. Is this a normal give and take scenario? I though the gutted main cats would increase my HP, not decrease it. Here are my dyno sheets from today. BTW, would resetting my ECU help at all? I haven't had the chance yet. The top picture is of 2 different days (today and Jan 18th) overlaying each other while the bottom picture is of today's 2 runs. Never Play Leapfrog With A Unicorn!!!
