e series engines run rich at higher in the rpm a mechanic told me, so it would only make it worse

it will run ok on 24lb injectors, using the fmu, a touch richer on idle but nothing to bad, thats depending on your base fuel pressure.

but considering your running boost, you can run the j3 with much bigger 36-42lb injectors (trim and adjust fuel map to suit) and chuck the fmu rubbish away and just run a normal reg..

Gday mate im running blue tops on stock el tune (fuel side) runs a bit richer but not much more, about the same as stock eb ecu tune around 13-14 afr at cruise. Allowed enough fuel for extra 2psi boost. Pulled 240rwkw on them sunday with 12:1afr @ 100+psi fuel pressure. Basically good for a small increase if you get them cheap but 42lbs + is the way to go in the long run.

The 24's will be a good suit with the fuel reg you have.. Even the stanfard 19s will work fine on low boost or low 200rwkw.. It's a proven formula.. You will need a j3 to have it running sweet though.. Best thing to do would be call who ever you plan on tuning it and do what try recomend fits in your price bracket.

Freight would be no more than $50 at most...

Seen way too many good engines wasted through ignorance ...

Sell the maf and recoup what it costs...With two spare injectors..
Which could be fitted up stream ??
Or just buy the 36 to 42 Lb injectors..
