42lb injectors and a single nozzle and an I tank pump should do 25+psi on your combo.
You need to see fuel pressure and methanol pressure in real time to verify the fuel system is working properly.
If the chip was burned with 25psi and your at 750mv now something is off.
Eric is not off on his fueling usually.
You can add and should wot fueling in the chip but if the pump or alky system isn't working properly then it cant add
