Mine was dyno'd at 380/375 using autolite platinum plugs gappes to factory spec. The only other thing I have over you is a Accufab plenum and BBK/Roush 75mm tb. Mine was tuned using a SCT x-cal. I would try getting it tuned somewhere else.

Is your tuner tuning with the predator itself or is he using a computer??

Eric, at Swarr Auto, uses SCT with his dynamometer. I had already bought a SCT tuner when I bought my supercharger so all he had to do was plug n play. I think he had software to run other tuners too. I'm not much of a guru on tuning but I see alot of other people with simular mods putting down simular hp/tq. You should be in that same area.

I've seen guys with 8 psi and the same mods putting down 380rwhp. I could've pushed 400rwhp with more tunning but I didn't want my car to blow up " WITH THE WAY I DRIVE " . Also, I didn't want to be the guy on youtube , blowing up his car on the dyno.

The reason I ask is from what the OP's saying, it almost sounds to me like his tuner is tuning through the parameters given on the predator. Any tuner worth paying to tune your car isn't going to do that, you could do that yourself. Like I'm sure when they tuned your car with the Xcal he wasn't using the Xcal, he was using the SCT Advantage software and loading that tune to your flash device.

I would find a new tuner. Your gap is too huge, your a/f is way to rich and no where near enough timing.
