Hello,
I've recently installed a 72mm ktuned TB. While in the process I also portmatched the intake manifold to 72 mm. My intake manifold is 2.5" and I bought an adapter that bottlenecks to my TB. I also replaced the stock injectors with TRQ 310CC injectors. I adjusted my throttle % by +44 which ktuned recommended but no luck. Ever since this upgrade, I've been getting knocks in cylinder 1/4. ( I Ithink a dangerous amount). I also should mention that in wide open throttle my A/F sits around 14-15 (should be ~12) I'm not sure why but I think it's just a weird airflow situation. Is anyone able to help with WOT tuning etc to get my A/F right? Thank u!
(attached is just a datalog of a drive I went on)
