I have been tuning my car from a 3 rd gear 45 mph roll. Boost is set using a mbc to 16 psi and if I see any kr, it is always less than 1 deg with O2 at around 770 to 790.
If I get onto it from a dead stop I get a touch of knock at the 1/2 shift but now I am seeing lean knock around 65 mph of 4.5 deg with O2 of 770 ish.
The obvious answer is alky but I have reached my $1000 annual budget already. Is there any thing I can do other than turn down boost to get rid of it?
