I am putting a Commander 950-19s (400cfm 2bbl TBI, 65# injectors) on a GM 3.4L V6. Holley's selection of base maps is great if you have a 350 SBC, but not much else.

Can anyone recommend one of the base maps that might be close enough to get this up and running, or do you have a map available that might be a bit closer than what Holley offers?

I already asked Holley of course, but they lived up to their reputation...

Thanks
Bill

Take the lowest hp base tune for a V-8 and then start by pulling 15-20% of the fuel out of the VE table. Spark map and Air/Fuel table should be about the same. Do the same with acceleration fuel too.

Holley Techs don't know much cuz they have no practical experience like most techs and their system, IMO, sucks. Just my 2 cents worth.
