I have b20vtec turbo, in a 95 del sol (was a b16a3 model). Have 450cc dsm blue top inj, brand new, stock fuel pump. Lowe is tuning it but says it is getting mad fuel cut after 6psi....Could my resistor wiring be wrong? My last car had same setup and was holding 11-14psi with no problem..? Im trying to reach 14-17psi on this setup so I know I will need 600+ inj and a walbro pump and 3 bar map, but I think this setup should at least hold 10psi...What do you think? leave a message here, text, or call, at 217-494-4865

Thanks, this has been a frustrating experience.(if you have anything I need, also let me know, its posted in wtb)

You probably need a bigger fuel pump to start. I had the same problem with fuel pressure dropping due to the stock fuel pump. The injectors and MAP will need to be replaced soon for the goals you want. 10psi is cutting it pretty close for stock MAP, pump, and 450's.

a 1.7 bar(stock) map can only handle about 10 psi max. So if your getting cut, then most likely your getting starved for fuel. things to look at will be duity cycle and fuel pressure just before cut.

450cc should get you to 300whp no problems. Were they flow tested? What is your fuel pressure at?
