It does have shorty headers on it, no cats though. We checked around the engine bay, too, and found an area where the block may be making contact with the crossmember at times. Hope to have that...

Hey guys, I'm working on a 5.3 with a stage 2 tsp cam. I keep getting knock retard popping up at various times during logging. I've attached a couple scans that show some KR. I'm not sure what may...
The logs I posted along with the current tune file show it stalling at the end of the scan when he gives it a little gas to take off. In the VE data drive log the injector pulse width goes way up as...
Good evening everybody,
I'm tuning my buddies L59 swapped 1980 GMC and it's proving to be more difficult than I had expected going in. I am fairly new so far but have successfully got my own 24x...
Checked the O2 wiring at the PCM today, all looks good according to my 0411 swap pinouts
Do you mean at the PCM? I have an extension on one of them but otherwise under the truck they are plugged in correctly. I can recheck at the PCM either tonight or tomorrow morning but it ran fine...
I agree. I'm stumped on that one.
For the misfires, I'll try to outline the scenario again just to help organize my own thought process
Cylinders 2, 3, 4, and 7. I find it interesting that...
Both of these logs are with it wired your way, with different inj bank selects
I found my old 0411 swap sheets from Lextech and it shows the same corresponding wire values for each cyl as what you wrote, and the same connector color, however compared to what you wrote 2 and 3,...
This is from the gmtruckcentral writeup, implying i should indeed swap the injector wires at the pcm for 2 and 3, and 4 and 7 but when i do that it wont run with the inj bank select set to SBC...
They are the round body truck coils, I believe d585 is the number for them
Checked my bank select to make sure, and those are the values I'm running
I don't know if I can be of all that much help since I'm just getting started with tuning but maybe I can help a bit. Looks like the tune is for a 4.8L and there are a few things that are a bit...
The coils are wired up according to the info in multiple write ups, each cylinder going to its respective LS pin designation with 2, 3 and 4, 7 swapped. I swapped them again to see what would happen...
Hello
I have a 1997 GMC Sierra with the L31 5.7 Vortec. Right now it is 0411 swapped, 24x swapped and I now have long tubes and dual 2.5 inch piping. No other major mods. I am trying to prepare...
