I've been successful with several MPFI conversions. I'm dumbfounded what was causing the flooding. The origins of the MPFI conversion were from HP Tuners.

I'm going to change to a l31 and wanted to go mpfi and trying to get every thing ready. Still considering a 0411 but have concerns about the 4l60e.

The 16197427 MPFI conversion is a good option for the L31. It the budget is available, an 0411 / L31 is a better option.

I have the 6395, would like the 0411but I'm concerned about the 94 4l60 with 0411. Time to check my local supplier, junkyard.

6395 can also be modified for MPFI. To the best of my knowledge, the 0411 only works with 1996 and newer 4L60E's.

0411 requires wire harne$$ work.

That's what I thought, ill probably modify my 6395 or a 7427 and keep it simple for now . What changes were made to the 4l60?

I'm not a 4L60E transmission expert, likely the 1996 and newer 4L60E's have different valve bodies. https://www.sonnax.com/units/455-4l60-e
