Edelbrock Pro Flo 4 EFI

Hughes recommended me ngk R5671A-8

I believe the hesitation comes from a fuel map not suited for the engine combination.

The edelbrock tech forum recommended me map 5016, but it felt worse. I was running map 5030 previously.

Based on the confirmation posted above I tried a map for a larger displacement engine, based on the fact that my heads are ported, has larger valves and higher ratio rockers. I used the 440 mild map and felt much better. One of the things I noticed is that the FT correction is now less than 30, when before it was always to the limit.

I will try the 440 race map. I think that will be the right one. Will post the results
