Just purchased '93L...have questions
I just picked up a '93L. Just as background, I'm familiar with carbed hipo buildups (I've done a 460, 390, and 408w) but this is my first performance EFI vehicle. Also, it has a Powerdyne (pulleyed to 9psi) which is new to me.
It had FRPP headers, offroad cat back, MSD with boost retard, 70mm throttle body, SuperChip, and an Eaton Posi as well.
Now, sorry for being vague...but it also has a pump wired in on a toggle switch...obviously to help with fuel volume.
From what I understand, the FMU is a 12:1 unit...I've only had the truck a few hours so info is a little sketchy right now. I saw 70+ fuel psi under boost so I guess that's a good thing with stock injectors. Set the boost retard at 2*/psi. It still pings under boost. My question is...how exactly to stop this? I didn't check base timing yet, but I'd think with boost retard it would be ok anyway. As for the SuperChip...it was in there when the owner bought it so he didn't have any info...I'm guessing it could be increasing timing which is contradicting the msd retard.
So...as I said...I'm an EFI newbie. From what I gather I could have it dyno tuned and a new chip burned to hopefully eliminate any ping on 92oct? I'm also considering going back to 6psi...it really is a daily driver and tow vehicle so I don't need to push it. Also, heard about guys using a powerstroke intercooler...any links to info?
Thanks for any advice...
