720 injectors

[GSX93DSM]

Have a question I plan on running 720 injectors and 17 or 18spi with a rewired 190 can I do this with the stock fpr.

Injector size is not directly related to pump size. You'll need something to control the big 720cc injectors, like DSMLink or DSMChips.

Are you upgrading turbos? If not, get 650ccs and keep the 190 and the stock AFPR for the EVO III 16G. You can tune with an SAFC and a logger. If you are upgrading turbos and plan to run on high boost, you'll need a bigger fuel pump (255+AFPR) for the 720cc.

The only thing I have for tuning right now is the gm maf with transbox

You'll need something else for 650ccs or 720cc injectors. If you choose to get 650ccs, you can zero out the MAFT and tune with the SAFC.

You can also sell the MAFT, and get the new MAFT Gen II, which is a SAFC and MAFT in one unit.

What are you plans? Are you upgrading turbos or keeping the EVO III 16G?

I say these are your choices:
1) 650cc injectors, a logger, SAFC and tune it.
2) 650cc injectors, a logger, MAFT Gen II, tune it (sell your original MAFT and make some money while you are at it)

If you plan to get a bigger turbo, you will need to upgrade your fuel pump and AFPR. CanadianTSi (damn, I use his name a lot), ran a 11.8 with a 50 trim turbo, 660cc injectors and a 190 pump. I don't think you'll need 720ccs.

Here is the MAFT Gen II. Do a search for "MAFT GEN II" and you'll find more info.
