I have a 350 HSR motor with alum heads and other modifications, including a custom chip and I cannot get the motor fully tuned. Unfortunately, all I have to work with is timing and fuel pressure. I want to go with a DFI system, but don't exactly know which system is the best. I've been looking at the Accel Gen 7 kit, but I also heard that Jet came out with a kit as well. I'm wondering if anyone has one or knows if one is better than the other. Next year I'm going to a 383 blower motor so this kit is a must have. Please respond if anyone has any info. on this topic.
