Horsepower TV dynoed an auto at 255 rwhp. 45 hp loss through the driveline, thats probably not too far off for an automatic. i took automechanics and we had a twin roller dyno. seeing anywhere from a 30 to 60 hp loss from crank to tire on an auto was common. about 20 to 40 for a stick. after adding the K&N intake, flowmasters, and a 75 shot of ZEX they got 336 rwhp. 81 hp total. not too bad. got 7 from the flowmasters, 12 off the K&N and the rest from the ZEX. no reflash either. supposed to have another episode on that. up the 75 to 125 with an SCT tune.... cant wait... :happyhapp
