Default 1-3* KR on the stock setup

so now that i have the Aeroforces, i can monitor some paramaters...i do not like the KR that i have

I notice that i always get KR on a 4-2 Downshift (1-2*)
i have seen KR while cruising down the road (1-2* at best then decays away)
KR was always present while Running at hte Track (2-3* in the higher RPM'*)

so how can i eliminate the KR if the car is already stock. Again i dont like the fact that the car is already getting KR, and i fear that if i mod, it will just magnify the problem if there is one??

FWI for cooler air a little further away from the radiator.

At the track.. drop a couple gallons of 104 octane in to your already low tank of fuel.

Check the plugs and wires ....because they are low mileage doesn't mean the gap might not be out of spec or a plug might not be in need of replacement.

Plugs, wires, do a good general tune up on the car, I know its low miles, but thise pieces, especially plug wire/vaccuum lines tend to decay without regular use.

I get a bit of KR at downshifts as well, but it goes down to zero as the revs climb. I think the most I've seen was 3 or 4 degrees....I'm stock for the most part too. I was told this was completely normal.

He'* getting the same situation as me.

Light throttle..cruising w/low engine load, under 7%...which is only maintaining speed. 1-2 degrees...and then it decays off.

Sorry Pat..you shouldn't have let your car sit so close to mine. Now..your White car is Cursed...lol
