Hello I have an 06 300 srt8 and live in calgary ab canada and at a high sea level 3500ft. I have cai and magnaflow exhaust i was wondering if u think that at this altitude it will have any affect the 93 cai tune? if so is there any suggestions on fine tuning other than $150/hr dyno time? I also from time to time have had the mysterious down shift clunk but not all the time and was wondering what is the conclusion on this issue.

If at altitude, you can try the 93 tune.
Log for KR and if none, you are fine.
Datalogging and a wideband are your best friend to dial in the tune.

Thanks

well thank you fine sir .And as for the down shift any more on that?

Oh, sorry.
First suggestion would be to make sure you are on the latest revision, also try resetting the tranny adaptives.

Thanks

I am running the 8r20.I did try the reset it was good then i retuned and it seems to come and go i will try another reset .Also i will try the upgrade to 9r02 this is the most current is it not?

Thanks Fred

Yes, 9r02 is current.

I was told to do some logging and have done so was told to look for KR was wodering what #S I should be concerned as if I am correct the KNK tol RET was reading 127.00?? i added fuel and have since pulled 2 degres of timing do u have any suggestions

Look at LT_KNK and ST_KNK, along with actual timing cyl. 1.

Thanks

I have logged and have seen the ST_KNK numbers creep up starting around 4000 from 1.5 to 5 under hard acceleration also have the gas fattened to 2 4 6 and will add a little more to see if i can remove it im running 94octane with 10% ethanol.any further suggestions as to what i can do but pull timing.
