The rotofab did add power over the stock box and hi flow green filter that the eforce came with. I didn't dyno as hi as before I had just filled up the day before on Sams Club gas the car really wanted to pull timing is what they said. There pretty sharp at powerfab so I trust what the tuner thinks is that I had a batch of bad gas or maybe even the guy put 91 into the 93 tank seen that before aswell. My original dyno was way higher.. the car didn't want to pull timing like it did yesterday.

These are 2 back to back runs on the same day.. so hopefully on a good day the car will be about 580 at the wheels.. but the test did show it adds power.. even with bad gas.

I imagine that the lt4 guys will pick up more with there setup for GM filter probably doesn't flow aswell as well as the hi flow from edelbrocks kit..
