It goes lean!!! Right before, during and after the IMRC point it is leaner than normal.
I tuned it out with the S-AFC. The kick is smooth now... Also the chip lowers the IMRC point and softens it (which sucks!!!) vs stock which changes the shape a bit...
I will most definitely be addressing the IMRC point and spark advance before it. Like will enough advance (over stock anyway) help offset no secondaries... It's not that your are NOT still using the long runners, just only "half" effectively getting there benefits...
Need to get to the dyno for some testing soon...
