okay I have a Greddy E-01 and it was working good. then i let the car sit for 2-3 weeks and now my high boost doesnt work i set it for 13psi it spikes to 13 then drops down to 9-10psi. so then i thought maybe i should put in my MBC from where i got the car so i did that. it went to 15 on secondary then droped to around 10psi.



has this happend to anyone? could it just be some kinda intake leak?

 

just searched on Rx7Club seems like its a leak somewhere

 

Sounds like a leak.. Check all your couplers.

 

okay all my couplers are fine. could it be my UIM gasket to LIM is shot? or would that cause a diff problem?

 

what else could it be besides the couplers and IC piping?

 

could be a lot of things.. i have a leak somewhere on the top of my engine, i can hear it and spray stuff and the motor sucks it up.. its either the secondary injectors or LIM, but i replaced the LIM gasket... 2 times.. so i'm thinking its the secondary injector grommet/insulator.
