I installed HMF Titan QS and Optimizer set at HMF's setting 4-3.5-4-3-3.5-4.5 but it running rich. Just wondering what other owners with a HMF Opt. have there's set at?

HMF Tuning

Our Tuning Settings were determined on our dyno at 900ft above sea level at 60 deg F with the stock air box. Mods may require different tuning.

Mode 1 4.0
Mode 2 3.5
Mode 3 4.0
Mode 4 3.0
Mode 5 3.5
Mode 6 4.5

still playing with the settings, but got mine running pretty decent and not much backfiring at 3, 2.5, 2, 5, 4, 4 settings on mode 1-6 accordingly. In Houston, TX

Still can't get mine dialed in. I thought EFI was going to be simple. I never had a problem jetting a carb.

Bump this up:

Anybody have any luck eliminating backfiring with this set up??
