14b ? and 16g?

[SnowBird]

14b question, to run at high psi what fuel mods do I need? Just a rewire? I keep reading the 450's are enough for the 14B but 15 psi is safe. next question, for a 16G are 550's as big of injectors that I would need? And what psi could I run the 16G at safely with a 190 rewired on the 450's? And I have supporting mods, all maintenance done including timing belt kit, 3 inch turbo back, MBC, gauges and such. Just trying to max out the 14B first, If I have to get a SAFC to max out the 14B Id rather just switch to the 16G at that time and be done with it. Thanks in advance.

Bumping fuel pressure helps a lot.An n/t fpr raises pressure about 10-12 psi and turns 450's into 505's.On my datalogger,it saves about 10-15% duty cycle.Only down side is you have to have a tuning device(safc,maft) to do this since it will flood the engine at idle and foul your plugs.
