AHH yes I forgot to add that in Thanks Motion427 for pointing that out. My tune was done (is still being done, he trying to nail down the Detanation problem, nothing drastic) By Allen Nelson from Nelson PerformanceMotion427 said:I did mine about 3 years ago.Lot more power,did not lose any MPG.
Nothing different than a 5.3L as long you get a 6.0L a late 6.0L.Some early 6.0L had a different crank that require a spacer.Mine is an 04 Avalanche,and I found a 04 6.0L LQ9.Did a cam change and a springs upgrade while it was on the engine stand.Did the change over in a day. Would need to retune the ECM to get maximum power.
Holy Cow . I completly forgot about the Knock sensors I took them outta my 5.3. Thanks #7Motion427 said:The knock sensor was picky on mine. LQ9 engine. It was too sensitive
You can tell that to Allen,that may help ya.
leave it to a canuk..Motion427 said:It was too sensitive

Then you shouldn't have any problems. Good luck with it.HitechRedneck said:Excellent! All that I want is a little more power with the swap (cam, valve springs, etc.) Already have CAI and exhaust.
