Hello all, new member here. I'm working on a 2001 Z/28. The attached tune and log is after doing the fuel trim adjustments as advised by HPtuners help section and if y'all think all is well I'd like to add timing. I am leary of doing so at WOT <3,600 RPM as there is already knock evident. This knock has sufficiently lessened since being SD tuned for FT, it used to be audible to the driver at these WOT engine speeds when it was on a stock tune. It had oil in the intake and now has a catch can and several seafoam aerosol top end treatments have been performed to remove carbon and residual oil. The car was fully stock when acquired and I've added a SLP lid, K&N filter, larger MAF ends, and 92MM throttle body. It has also been driven ~300 miles to learn LTFT after the final tune. The engine has already seen A LOT of knock at the 1-2 shifts and on top of second gear pulls as we drove it hard with audible knock for ~ 1 year. If it goes it goes, we have a shop and a 6.2L ready to go in so taking a calculated tuning risk at this point is okay with me I just want to head in a productive direction. Thanks!
