I just installed 100% injectors in my truck and been doing my own tuning. Running Les' s gift tune timing table and duration table which I decreased some. Tune runs awesome but seem to have a rattle at low rpm low throttle and at idle. I'm thinking might be in my timing. I'm having a hard time understanding the timing calculator. Any help, suggestions appreciated. 100% injectors, lift pump, built trans, stock turbo for now.

Its not your timing...its pilot injection pulse being too low. Log it and I bet the rattle areas have less than 230uS of pilot.

And when it comes time to show appreciation for the help we've been given by those with knowledge, people seem to disappear. Shame, as it could really help people referencing this forum in the future.

Sorry guys I started this post off of my buddies account since I didn't have one and never got on here. I didn't log the tune I had at the time. I just bumped up pilot a little and it helped so kept after it. Dialing back my injectors to match my turbo kinda threw me for a loop.
