Tomei SR7960 Overboosting?
Looking for some help.
91 240sx
SR20det
Yellow STi 550 cc injectors
Z32 maf
RSenthalpy tune
Powermaxx downpipe
Isr blast pipes (temporary)
Aem boost gauge
Walbro 255lph pump
300zx fuel filter etc.
Under full acceleration the boost gauge is saying 20 to 24 psi and I have the plumbing of vacuum directly into wastegate actuator on the tomei.
I did not adjust the actuator myself.
I can get pictures of anything requested but all I can think to do at this time is pull my exhaust side and go externally gated. Unless someone else knows something that I'm missing.
Much appreciated I don't want to boost spike my sr20 into a scrap bin
