How much psi safetly on 2.3l with stock 450's??

[000triple000]

2.3l, walbro 255, stock 450's, greddy 18g turbo, Ecmlink v3 form dsmlink.com (no fuel cut). How much boost can I make off of these injectors, Ran out of money from build, 880's coming soon, But anyways How much boost can I get off this safetly?? I want to run 15psi but no more anyways, is this possible??

I do have a knock off fuel pressure regulator with a gauge on it, and also i ordered dsmlink and it comes with a pretune, I set it at 2g maf, stock 450's,6bolt computer (6bolt swap), so im hoping that will have a good base tune will it matter considering mine will be a 2.3l instead of 2.0l???

Yes it matters, and no you probably aren't going to be able to make 15psi on 450cc injectors with an 18g and 2.3L.

Do you have a wideband?

I wouldn't risk it. I maxed out at 14 psi on the 14b turbo with stock 450's, and with an 18g that's a LOT more airflow. If it were me I wouldn't run anymore than 8-10 until you get injectors.

More fuel, what are your mods i didnt look, dont do it backwards and have problems. Get the tools you need to first then go from there, there is no rush, I took my time and spend money on maintenance, lots just to keep her on the road, now shes done time to have fun.

yes I have wideband. I will look at the, My car is in the shop being built getting it back monday finally just tring to get some info done before i get it back.

its an analog wideband and i just dont want to lean out and blow. Does a motor blow up instantly when you START to run lean or if you just mash the crap out of it and running majorly lean then it blows up instantly ???? If it started to lean out and I obviously would let off the gas, I don't know about it never had it happen to me before so I don't know how that works, any help please??
