Well, i searched because i saw a thread about this when i joined but didn't find an answer in my search results.
I got an AFPR (aeromotive) from import evolution a few months back. When i first installed it i could not get the pressure to stay the same. I would set it to 43, it would fall to 35 after a drive. I readjust it to 43, the next time i pop the hood it's at 50psi. I eventually left it alone thinking that the springs and such just needed to seat in and it would steady out.
Well, lately I've been having major issues with my tune being inconsistent. It's most noticeable at idle where the small change in pressure will take me from 13:1 AFR to 18:1 when the AFPR goes kookoo. Then some times it's back to 11 &12:1 at idle. It's also noticeable when watching the closed loop correction as well, but it's minimal at WOT because of the large pulse widths and running real rich to start with.
MY QUESTION: Is there a fix for this or should i call IE and hope they still honor a warranty or something on it? I hope there's a fix, because i hate having to ask a vendor to take something back after so long, plus i know i hate the waiting on a new part, shipping one out etc.... petty reasons really.
