I just dynoed my car again....
on the UTEC and tune!!! That is my next route.

I was thinking about going with a set of hi flow cats instead of testpipes because I don't want it to be too loud. Of course it may be too loud for me with hi flows as well. I think it sounds great now with just the headers and the Borla TD. I've read that it sounds even better with hi flows but I would like to hear it in person before installing a set on my car.

Now, should I just get a Technosquare reflash or am I better off with a Utec?
Keep in mind, I live in RI and I don't know of a Utec tuner in the area. I also don't plan on doing anymore performance mods. I would love to go FI one day but that would be years from now if ever.

It appears there was a 13F difference in test temperatures that would decrease total power torque and HP by >1% minimum. You didn't specify barometric pressure so that could add or subtract some........~~2%.
Where are you measuring A/F ratios hopefully not at tailpipe?
POPCHARGER...........with a cold outside air kit........hopefully?
Repeatabilty on the same dyno is 1-2% with same tires.

I have a feeling that hi flows will still be too loud for me. Since I have a roadster and mainly drive it with the top down I don't want it to be too loud.

The barometric pressure was about the same. Although the humidity was much higher this time! I don't know how much humidity affects performance.
The A/F is being measured at the tail pipe. How else could it be measured without modifying the exhaust?
All I have is the popcharger. I don't have any "cold outside air kit". In fact, I've never heard of one. I thought the factory vent provided cold air. I know there are ducts you can install in the bumper but that is all I've heard about.
I am still running the same rims and tires as last time. The tires are worn more now but I doubt that would make a difference.
I would like to go back to the dyno on a cool dry night just to see what happens. If my results are similar then I guess a flash or programmer will be my next step.
This is one of the down sides of living in RI versus CA or FL. There aren't many, if any, Z tunning shops that I know of in or near RI.
