So, I bought a 2002 ZO6 about nine months ago...and so far have only discovered a callaway honker intake, offroad xpipe, and 160 degree thermostat...curiousity took hold today and I got it dynoed at PSI Motorsports..just a couple pulls to see what it was making because I've been wondering if it might have a cheater cam or something. The first pull was 391rwhp & 375rwtq..immediately followed by 389rwhp & 371rwtq...is that normal for as little mods as I've named? I hope so...cause that just means I have that much more to gain...but does anybody know exactly what a honker/xpipe/thermostat combo should put down????
