Drove in and started with 385 RWHP and left with 424 RWHP in 102 degree heat. Definitely feels peppier and hopefully wont code anymore. Saw a set of Shelby mufflers (used) on the floor and had those put on to replace my flowmasters. Lot quieter in the car and the ^#%$^*%$#*^ drone is completely gone. Tuner said mufflers would only suck out 2-3 hp so preferred to eliminate the drone. Hope to have my first SCCA race Sunday and test it out. Edelbrock marketing appears to be full of crap. The Eforce ads say 5psi and 466 bhp out the box. I am pushing 8 psi after the intercooler and getting about 470 bhp after a day of tuning.
