I dynoed my 03 yesterday. This was my first time.

I ran a 389.7 RWHP with 358.7 ft-lbs of torque. My max A/F Ratio was 17.5 at the start then ended up going all the way down to below 10. I'm running really rich at the top of the curve so I'm sure that hurt my HP. Do these numbers sound right for my mods. Bassani X with cats, and cat-back, and Steeda CAI.

I also noticed that my RPM went all the way to 6.78. My curve seems to drop dramtically after 6500 RPMs. Could the rev limiter possibly be the cause for such low torque numbers? It looks like my curve was still going up until I passed the 6500 rpm mark. Thanks in advance.

I think you definitly need a chip to flaten out the A/F. It's way to irratic. Plus it looks like the X-pipe and Cat back took some bottom end torque away. You didn't break 300lbs until around 4400. The chip would also help that, That would be my next step. I would give JLP a call. Or if you prefer another tuner try them.
