My 5.0 was running a tad rich before the swap from the OEM 55mm unit to a
73mm C&L unit (both calibrated for the OEM 19lb injectors).The 73mm MAF made a noticeable difference in power, but now I'm noticing more black smoke out the pipes.
Look at my Sig for my 89s mods. Oh, and yeah I reset the ECM...
What gives here ??
