make sure you have some kind of fuel and ignition management to be on the safe side. but if you want an investment that you can use now and still be good later get a wide band o2 sensor. Most people think if u put a air fuel ratio gauge youll be set but it's not accurate unless you have a wide band o2. it's good investment for tuning..

+1

310cc injectors will be ok until around 210-230 whp.
A jrsc b18b at 7 psi will only make around 200 whp if you are lucky in florida heat. You may want to look into the LHT JRSC cooling kit.

How are you getting the additional fuel? Boost dependant FMU< additional injectors, Hondata?

Before you invest any money into your setup you should perform a leakdown & compression test on the motor to see if running a random chipped ecu without a proper tune has done any damage to your motor.

If the motor appears to be healthy, you then should remove the fmu & get the car tuned on Hondata, Ectune, Neptune etc..

You should also consider using 440cc injectors as you will be pushing the 310cc injectors if you decide to go up to 10-11 psi...

If you have not already, you should install a walbro 255lph in-tank fuel pump.

A proper tune with an fmu ?
You can theoretically go that route but I would not recommend it.
