Wow this seems very familiar to what ive been experiencing. Glad to see you figured it out. Hopefully i will too soon.

Just an idea but i used some very fine sandpaper to clean up the sealing surface, then put a thin coat of oil over it then poped the seal on

Ill try upgrading the wire first, the one thats on it is an 18gauge. then if nothing improves ill pull the alternator. I see were the alternator could be causing this but do you think it is IJ?

For sure the alternator?

I datalogged a run and at idle their are 11.7 volts, the biggest drop is to 10.5 at 13psi. Can i eliminate the map sensor as the problem since pressure showed up on the datalog?

That fix your problem?

Any vids on this said exhaust

Thanks for the notice, i might just remove them. Runs fine out of boost

I am getting things set up for that now, ill probably pull the alternator and take it by autozone and see if they can check it out, same with the battery, run new power and ground wires the ecu and fuel pump along with the 12V mod. HOPEFULLY this cures it. Ill check the lights out tonight...

When i start the car its in the 11's or high 10's. Ive noticed at idle the car runs richer than usual too For what its worth i had to jump the battery before it would crank earlier this afternoon, but the interior lights were on all day yesterday.

Yes, i think. What should i be looking into? maybe an alternator, or wiring

Ive done some checking and the ecu is getting its power straight from the battery, In boost its only receiving 9.8 volts i believe. Could this cause it? haha

Oh gotcha, yeah if its got access play then definitely. Have you talked to a machine shop?

Mine too ;)

Im going to try the 12v mod, but since the walbro ran fine i would think the wiring is okay. But the TT pump is bigger so i guess it would require more. Do you think that the stock wiring isnt delivering enough juice to the pump and thats whats going wrong and why im going lean?

Yep that was before i actually installed it

Its been running off the original wiring without the 12v mod. Does the TT pump require at least 12v?

Nice thead!!, any updates? or videos?

I know most ppl run new valves springs and retainers, but valve guides too?
