@bentune: During the final stage of tuning this Silverado, I noticed a trend in the VE table that looked unnatural. I had a suspicion what the issue was but needed to verify with a gauge. Just as I thought, the fuel pump wasn't keeping up under full throttle. it isn't unusual on a combo like this for a stock pump to be inadequate. a simple walbro pump + a hotwire kit will be installed so fuel supply will be sufficient and this truck will be good to go. #bentune #hptuners #dyno #tuning #mustangdyno #dynotuning #gm #trucks #Chevrolet #Chevy #Silverado #lsx #DIY #howto #hopethishelps #mechanic #mechanicsoftiktok #racetruck #LFG
Are the 50# GM injectors a good choice to upgrade my stock ls2 injectors? I’m at 84.5% dc and 16ms pw at 6k rpm Looking for something with good data and not $600+! Thanks Ben!

That’s probably what happened to mine, I did an Ls swap in my 69 c20, it sat for a year and now no fuel pressure but you can hear the pump running

Ran into the same issue when I put a TSP MS4 into an LS1 with ID725 injectors. It was good until a WOT pull above 5k.

So I’ve seen a 4th Gen Fbody with the in tank hose split and create a horseshoe shaped A/F ratio where the split would open and then close back which took forever to figure out. Great info!

when the pump gets replaced, does it need to be re tuned?
