Message	just installed new 1/4 inch wg actuator hoses with .038 boost jets. did two pulls. boost peaks at 15 and settles at 14. puts a big smile on my face but i want opinions on how "safe" this is with my mods cause I dont have a wideband. timing is 15 degrees, dual jwt pops, selin trans, Z1 ECU, stock turbos, stock injectors, Z1 SMICs, NGK PFR6B-11B spark plugs gapped .35mm, gutted pre-cats, gutted main cats, borla cat-back. I'm going to check fuel pressure this week before doing any more wide open pulls. As long as I maintain about a 43.5 psi variance should i assume im good cause i dont hear knocking or pinging or hitting safety boost ect... Very soon going to purchase 2.5" testpipes but after that whats going to be my next best bang for the buck? thanks
