Hey all, I took my car into a local tuning shop to get a baseline dyno done. They are using a Mustang style machine. Another member ( Velose) also got his car done there so I figured it would be a good comparison. Well my car came in at only 302 peak HP. I have a B&B cat back w/ a res. and a cone style air filter instead of the stock air box. Velose's car stock, no mods came in at 326 peak HP. So "WTF" is wrong with my car :confused: ???? The tech that did the dyno said that my cone air filter may be the problem (already in the trash). I noticed when we were done that my heater and rear defrost was on, would that zap any HP? Looking for some answer begfore I put my Maggie on, so please chime in with your thoughts.
