Re: Anyone with a Procharger and EFI?
Hello, I have a Procharger D1-SC on a HO 454 (8.75:1) with retrotek speed TBI system. It is an older model and autotunes. I had to increase the size of the injectors to 92 Lbs. each and get a new load from Retrotek. Once started it began to autotune and runs well. I live in Denver so having the ability to autotune when I go up in the mountains is a plus. IT could use a good final tune by an expert but haven't found a good tuner in Denver yet. I have run mine with and without a intercooler. Little more lag with the intercooler. Another reason to find a good tuner. All in all it works well. I wish one of these magazines would do an article on my set up. They have done a D1-SC with a blow thru with a cam change and got 720 HP without any problem. Sure would like to see what they could do with a FAST, Holley or Accel system?
