Homebrew turbo question

Hi I'm running a 91 1.6 with a t25, 255 walbro, 230cc injectors, a msd box, a fmu, and I replaced the stock fpr with a gauged one. I noticed when the cars idled at 30psi when I turn the release **** on the fmu it goes up by like 12psi. Im really poor and this is the only bandaid i can afford. How do I tune this thing?

Take everything added to your car that is part of a turbo setup off and return the car to stock. If you claim you are as poor as you say, then you cannot afford a turbo miata.

Why did you replace the stock FPR?

there's no reason for any of the BS in this thread.

Sell FPR, FMU, MSD, and Wally for $400. Buy MS kit and build it while you drive around stock. Save up to buy injectors while you are building your MS. Win.
