Need Help

[Syndicate1924]

Just bought a 2000 L. The guy I bought it from didn't know what performance had been done to. He drove it once, and it was in the garage for 3 years. It has to have a either #4 or #6 pound pulley on there, because the boost gauge jumps way over the ten right? Would my L. had to have been tuned? because I'm thinking about getting a tuner for it. :shrug:
Any help would be appreciated, thanks!

Look under the pass. side kick panel to see if the pcm has a chip in it. The stock boost gauge is iffy at best. Here is a pic of the upper and lower stock pulleys.

^^ What he said. If you don't have stock pullies, I'd have a tuner at least look at it at some point.

^ what nole said. Post pics of your pulleys. In the mean time try to stay out of boost until you get your truck checked out. Is there a wideband gauge installed?

No wideband gauge installed. I'll post pics this weekend of the pulleys

This is not mine, but the pulley set up looks just like mine.
