Tony, yes I still have the stock cats and that's why I am thinking of putting in hi flow cats in the next month. I was pretty disappointed in my dyno results too. One problem I think was that the shop that dynoed it used only a small window fan and had my hood closed during the dyno runs. Also, I found out just before I put my Viper in storage this year that my headers are leaking and have fried my O2 sensors because of the heat. Also, the front O2 sensors were not put in the right location. I am having all of that corrected in the next month along with installing the hi flow cats. Do you think the leaking headers and fried O2 sensors are what is causing my power loss? With my mods I expected a bit more HP and torque also. The car is one of the first 50 GTS's made in 1996, so maybe they didn't quite have everything right on the first few they made too, I don't know. Having worked in the auto industry for the last 8 years myself, I know that sometimes bugs get worked out in the first few weeks of production of a new vehicle and that's why I am afraid my car just may not have as much power as other GTS's. But, I hope my repair to the headers and O2 sensors along with the hi flow cats pick me up some power this Spring.
P.S. Does anyone else out there on this board have one of the first 50 or so GTS's ever made in 1996? I guess they went mostly to Chrysler execs and VCA Presidents from what I am told. I am curious what those cars are dynoing at.
