Hi Everyone,
I went to Heffners 10/13/04 to have car tuned again and blower pulley changed to 10lbs.Jason was able to get 643.8hp and 667.1 tq. I was hoping to get closewr to 700 and Jason tried for hours. He told me the Random teck(ceramic cats)were not rated for more than 650(crank)hp and thought this was holding back. I went to a local car show today and they had a Mustang Chassis Dyno so I thought I would give it a try. The dyno guy almost had a heart attack when I made the first pull and the car made 558hp and 643tq. I thought this dyno must be in need of calibration or there is a big difference in the two brands. Well after first pull his helper said I had something comming out of the exhaust so we checked it out and it was my HI-FLO Cats. This may be the reason for such a difference in the #s. Now I need to decide to either go with no cats or upgrade to better hi-flo cats. The car seemed very loud on the way home as Jason said it would be with no cats. Heffners is also a great place!!
Thanks
