What is causing engine to skip?
Please take a look at the 12 sec YOUTUBE video link of this problem. The engine will momentarily shut down or skip for no apparent reason. It does not happen every time I make a run, but it does happen often enough to be a problem.
This is a conversion and the engine is a 2009 rxt 4-tec with 60 lb injectors, X charger, external intercooler, reflashed RIVA ECU, CDM fuel tuner.
AFR's are good and I just re-installed the fuel map. I also installed a new AGM battery and filled with fresh gas.
Has anyone experienced this?

Check coil packs make sure they aren't rusting and they are cleaned along with new spark plugs... I had mine do that same thing at same rpm .

Also check Plug Gaps and make sure they are not too big. Try closing them up to 20 thou.

I replaced the plugs. Here are the ones that came out. 2 were gapped at .028 and one was at .034 (too much!). I gapped the new ones at .026.
