hello everyone I have a quick question. when I pulled the tune off of my truck. it showed that the pcm is a p01 for a 4.3l v6. but I have a 2001 Silverado which should have the 0411 pcm and a 5.3L...

Thanks! Right now my maf isn't in my tune I have it shut of and am tuning just off of VE tables. But I plan on hooking it back up. So I have a new question trying to figure out this timing thing.....

Thank you for that. Appreciate it. I'll check it tomorrow. How do I check the intake air with the heat gun where should I get the temp from?

Thanks for the replies. It has a stock intake on it. With a k&n drop in filter. Electric fan swap, dougs. Mid length headers. And a 3" exhaust.

So 7.3ms. Does injector cycle % matter as much? And I get that it will vary I'm just curious. I'm only at 5.2 so I'm no where close. I was just curious how much injector I had left. I'm at 24xx psi....

Okay, how about injector cycle. What's the highest percent you want to have for the stock injectors?

So, I have a question for those of you that have tuned an lnf. What's the max fuel rail pressure you guys have ran on the stock fuel system? And can someone explain what raising the fuel rail...
