Just so you know your MAF will be freaking out and you will end up fouling your plugs if its running rich rather then lean. If it will start I would say at an idle for a minute to check for leaks you will be ok, But I wouldnt drive anywhere until you get it tuned.

IF that MAF is calibrated to those injectors, you should be fine.

I went from stock maf and 21lb injectors. Put my PMAS blow through MAF in and 42lb injectors, with the MAF calibrated to the injectors size. It started, idled, and drove absolutley fine without any tune.

Idk if you went from draw through to blow through? But make sure the IAC is going after the MAF, otherwise itll stall out.

i don't think the slot style maf's come calibrated to any specific injector, but i could be wrong.

i'd call my tuner and ask for an email/startup tune personally.

You did not even tell us what size pipe the hpx is in. I would not drive it. Or if you know that your load with failed maf table is correct you could leave the maf unplugged.

Get a base tune emailed to you from your tuner. I wouldn't start it.

Pretty sure the MAF hasn't been calibrated to injector size for a long time. Get an email start up tune from the tuner would be what I would do.
