I'm surprised how many out there have had the same experience and have emailed me for my experience with the 2.9 Whipple install. All I can say is had I bought the Tasca kit I would have paid a bit more but I now see its a better set up. Dennis at Tasca is still coming up with little bits calibration that he is sending me to relieve a couple of problems. He is being very kind in helping me even though I didn't buy my Whipple there. But I will make a few purchases soon like the fuel pumps and maybe injectors. For sure there are others that can resolve problems but Tasca seems to be dialed in on the Whipple. Anyone having the issues can P.M. me.
