AHHHHHHHHHHHHhhggggggggggggg. your 16G should e no higher than 23-24PSI IMO but you really need to find out if th car has a fuel pump and injectors before you run that high your gonna kill you motor real fast if you dont

 

it has the the upgraded fuel pump and injectors

 

ok now we are getting somewhere. what pump and injectors? and is the car tuned? if not you need a tune and your looking a some more power

 

ill have to go out and see....the car has been tuned...has engine work.....

 

Well you nee to tell us what is done to your car so we dont need to keep asking one at a time.... what else does it have done? so far id say you are safe to run the 25PSI setting as long as your running 93 octane or higher, BUT does it have a wideband o2? do you now what the AFR is tuned to. If not then your next mod needs to be that so you can make sure it is at a safe ratio

 

Here are some pics of it.....if you know what they are ...please let me know

i think they are RC Fuel injectors (550 High Performance)

Well i have a Digital Air/fuel Ratio Meter.....i dont know if that tells you anything

 

well they are obviously rc, and most likely 550's. I dont get the "high performance" part since they are 550's but whatever.

Oh and sebba, i know a guy who made like 440hp on stock 7 bolt internals on a FP Green. Without crankwalk so far.

 

if it reads in digital like a number than yes it should be a wideband. your wide band should read between 11.1-11.7 when you floor it all the way to red line if it is higher than 11.7 you might be to lean and could be dangerous if it is less than 11.1 then you are running rich which is not bad but your robing some power from yourself.

I would try your 25PSI setting and watch the AFR reading or videoing it and see what you have for a reading all the way up **Note if it goes to 12.1 and stays there you should get off the gas and richen up your SAFC corrections

 

The second picture says it all. RC 550 injectors. Do you know what type of fuel pump. Im gonna guess since he has all these mods that you have a walbro 255 since you have a fuel pressure regulator also. So far its seems you have the supporting mods to run that boost then. As long as it has a good tune for it. Because a change in boost means that the tune must change as well. So the afc must be tuned for the high psi which means when you have the switch off your probably running really rich
