so heres my problem, my CA18DET is running really rich yet i have found and fixed all boost leaks, check most sensors, and made sure the MAF is at least 10-12in from the turbo...

so hear is the deal resentaly i got a SMIC to get rid of my FMIC because it was bulky, yet when i had the FMIC i was running the MAF blownThough and it ran great, i could just run the MAF on the cold pipe again but id rather not do that again.

i have heard some Supra MAFs work but i cant find any info past that.. any info helps or suggestions

Was the engine tuned to run the blow through setup? If so, and you move the MAFS to draw through, that can throw your afrs off. Not to say it can't be done, but I've never heard of a Supra MAFS being used on a Nissan.
