According to my plugs the air distribution on the stage 2 conv manifold is way off. Cylinder 3 lean, cylinder 1 and 5 rich. Clyinders 4 and 6 lean clyinder 2 rich. I can see why number 4 and 6 are lean on pass side but you would think 5 would also be lean. I just installed EGT bungs in each and will log some numbers. The mainfold appears to be trimmed 1" and fits under the hood with the Precision 90mm TB. Has anyone else noticed this??? Injectors were just cleaned and are matched within 2 %. Looks like I will need to trim some fuel with the FAST system.
