Thread: 3.4 Installed, still have KR and high boost-now what?

not to kill your sale, but a 3.5 probably wont make enough of a difference to matter. its just cold outside and hes running more timing/boost than normal. in the spring/summer i bet the car doesnt knock if it had a good tune.

It probably doesnt help that I am running 200 more RPM's either at the top end. In first I only get just over 1* of knock and towards the top of second gear it starts getting bad. I will just take it easy most of the time until I get a custom tune.(Fosho or FastKatt maybe) Don't know for sure as I have talked to neither of them, but it seems the best logical thing to do. So is it best to tune it in the winter, summer, spring, fall or does it not matter at all?
