LBZ mouthpiece and intake installed and now motor boggs down

[jeremybaumgardner]

I put the lbz mouthpiece on and also an lbz k&n cold air kit on my lly and not it doesnt run right. it boggs down sometimes but then other times it runs better than ever. I dont know whats going on with it. I have taken it to the dealership and they rescaled the MAF with the lbz tables and it did get a little better but still not right. i have also cleaned the MAF sensor several times to make sure that wasnt my issue.

Anybody out there have this problem and can help?

Thanks

Few tips that may help, but your question isn't really EFI related yet (although I would suggest getting a DSP5 setup to take full advantage of your LBZ intake).

1) Swap out the K&N for another setup (Banks, S&B or even the stock LBZ intake work much better)
2) Make sure you have no air leaks anywhere and that everything is buttoned up tight
3) Clean your MAF well with non-chlorinated brake cleaner then have someone with a V2 take a look at your sensor voltage (if bad, replace)
4) Check for any other OBD codes in the ECM
