Help with fuel/n20 problem

Ok i have 95z 383 heads/cam with tnt 150 shot. Installed walbro 255 36lb injectors. ON the dyno the car would run pretty lean on the n20. Car made 550rwhp on spray. I dont currently have a fuel pressure reg or gauge so not sure what the fuel pressure was. My question is do you think that a racetronix plug and play would be sufficant in feeding the n20 or will i need more pump/ fuel rail modification? I plan on adding the gauge/ reg soon so any suggestions on what to get would help. Thanks.

The racetronix set up will be enough to handle what your wanting to do. I would say that you should up the fuel jet and see what it does on the dyno.

You already have a 255 pump in the car the Racetronix is not going to provide any more than that pump since it uses a Walbro 255. You have to find out if you are dropping pressure first. Then we can determine if it is a supply issue or a tune /jet issue
