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. https://www.nopistons.com/forums/pub...1047683358.gif https://www.nopistons.com/forums/pub...1047683358.gif https://www.nopistons.com/forums/pub...1047683358.gif



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.
