Make sure you have good flow and smooth plumbing for the intercooler system. If you have the lines going up and down to get around the rad/grill area it can effect the flow. Seen that a few times on...
No, uses a rubber grommet.
You can do a ton of stuff before changing injectors let alone the pump.
Good luck with acting out on your "reading". Check out Lingenfelter as they've done lots of them and have parts waiting that work with proven results, I've installed tons of their stuff. Air intake,...
One from a 97-00 C5 will work. Get the pigtail as well so you can wire it in nice.
Installation can be from 9-3 o'clock with no issues. As close as possible to the factory sensors is best, and before the catalytic converters of course. You can use the factory locations, but you...
This means nothing. Just because your prior setup was good, doesn't mean the tune was correct for the parts you had installed. His data for these injectors is very close if you were to install them...
What car are you using it on?
Di-electric grease used on the plug end of the wires? Fill the end of the boot up and click it back on. That has solved our issues on 95% of misfires we see on stock to mild engines.
Make sure fuel pressure is at 58psi and the wideband sensor is warmed up and ready to read when you kick the key over. Wideband should be reading high 12's to 14's on the initial running to prevent...
Go to "Engine Diagnostics"-"General" and put your cursor on the P0121 items and read the bottom description and do what it says, see if that works for you.
Also, the bog is probably because you are...
What does it have for a reluctor wheel, crank sensor(color?) and cam gear(1X or 4X).
You can disable the DOD if that's what you want to do.
Should be 55-60psi. Ideally 58psi.
Use the LS1 knock sensors and mount them to the side of the block where the LS3 ones are...you will need to drill and tap the hole bigger for the LS1 style thread. Racetronix sells an extension...
A good flowing air intake will make both of those without requiring a tune. I recommend a sealed air box with a dryflow filter like a Volant, good flow, no oily air filter to deal with. Don't bother...
What does it use for a crank reluctor wheel and cam pickup? Computer needs 24 tooth crank input and cam is 1X input. Engine is 58 tooth crank and 4X cam. Maybe you know this, just starting with basic...
Assuming you're using a LS1 block, does the LS3 cam have the cam pickup on it? There is a few things that would cause issues with this setup; the above concern, wrong injector data, bad MAF data from...
Do what we suggested and see what happens.
Very true!
What is the mileage on the car? Any odd sounds from the engine? To determine false or actual knock, cut the timing down by a sufficient amount like 10 degrees in the suspect areas, confirm good...
Or just run injectors that you can properly calibrate for. A 60lb injector is good for what like 800-900hp or more at 58psi. You have is a stock 5.3 with 10psi looking at your sig. can't see that...
Do you have the right cam and crank sensor setup? You need to either swap the crank reluctor wheel to 24 tooth or use a signal conversion box. The cam needs a 1X cam gear with the right adapter...
Fix the white smoke first. What are the outside air temps when running the car? It's not just cold weather exhaust condensation is it?
