Noooooo. You need them. If you block and jet up, you run around town with 80's in the front and probably 10-1 AFR. Generally jet down, then larger PVCRs. I try to keep them small so the motor doesn't load up when it opens.the pvcrs were 5/16" WOW you must have had some gorilla holley "tuner" working on it earlier. I thought you just plugged the pvs and jet it up with a blowthrough setup. Those pulls looked extremely quick and I wouldn't be surprised if the dyno didn't apply the proper brake force, the clutch and/or tires slipped, or some combo of the three

. I can say, the car not even being tuned runs 10 times better with the turbo, so my guess is that the blower doesnt need the same amount of fuel as the turbo does
