Morning all,
I've been having some issues with my daily tune for my Quadzilla. I have +50hp injectors that are 4 yrs/20k miles old and have had the Quad for about 2 years now. I can't seem to tune out the smoke In the 0-5 psi area on tip in acceleration. Cruising is clean and at 0-3 psi but anytime I'm hitting a small hill or pulling out onto a road and getting onto it there's a decent haze its not a black out but its enough to be confused/concerned about. It doesn't seem to clean up until 15ish psi. I don't know if pop pressure would be low or if my injectors are a bad set. Also I could have sworn I saw @dieselautopower mention that they updated their injectors to be cleaner semi-recently. Understand that I'm not looking for free replacement or anything, I got them in 2017, mine are out of warranty as far as I know. I am just looking for info right now.
I have been running a 90% start to the fuel table, plus 1 each PSI until 10 then 100% flat from 10-15 then +2 from 15-20 psi, then plus +4 from 22-30+. (previous to noon today)
Maybe I have my timing messed up?
At lunch I'm gonna try the tune below.
