Anyone know anything about the CobraFi2000R, the three pod device? I have one, made mods....thunder mfg tornado(with gasket), cobra scalloped slips, wrapped exhaust, plugged AIS, I have played with tuner, seems to run fine, but still get popping under @2000rpm, regardless of what gear it seems. I am going to seal pipes where slips meet, and put in new header gaskets(I remember when I removed to wrap, there were no gaskets),and I run 89 octane. if anyone has this device what are your settings? If not any help appreciated.
