You might need a bigger fuel pump you really don't want to starve your fuel but you really need better intercooler piping for that big turbo. He also needs to tighten his exhaust bolts again and torque them. The one in the picture is threading itself back out. That can cause a boost leak. He needs to take the H box off the intake. That black box on the intake side of the turbo is not needed anymore. needs to replace valve cover breather probably upgrade to a supra metal pcv valve. Needs atleast 2.5 to 3in exhaust. If you can get a rx7 vaf and tune it with a wideband sensor probably 460 to 550cc high impedance injectors

A wideband is an acurate way of reading your air fuel mixture. Narrowband is what you see in cars without turbos that just want guages and you just clip the 02 wire and it gives you a narrowband reading. Narrowband is so un acurate. I was told you are supposed to tune your vaf for 14-14.5 at idle and 11-12 at wot and something else for cruising. Its a lot easier with a standalone ecu but can be done with a vaf.Cincinnati, ohio Bengals for life
