06 5.3L Silverado Engine Model

[LBZ]

:master: I know nothing about tuning engines with spark plugs. Can anyone tell me what the Engine model would be in an 06 Silverado 1/2 ton with a 5.3L? Can it be tuned with EFI? Are they any big differences compared to tuning diesels?

Thanks

yes you can tune it with efilive gaines arent like your lbz. around 10 to 15 on 87 20 to 25 with 93.doing some shifting stuff helps firm up shifts and making kick down come on higher rpms helps when passing. i have done 10 or so and they all like it
