just was curious if i using the stock 02 would be safe for normal driving on a 11:1 z6 with the 95300 cam and bolt ons or if i should disable it and tune all my tables off the wideband. will obviously be using 93 octane

 

Does this REALLY need to be answered???

 

im assuming your being a smart *** and saying it OBVIOUSLY does but people run near 11 to 1 mini me swaps all day with out a tune.

 

And they probably run like *** and blow up shortly after. Do it right the first time, or enjoy doing it all over again.

 

You'll be much happier with it tuned.

Besides running the risk of blowing it up eventually, you also risk damaging parts or reducing their efficiency.

Get it done and then enjoy your new motor!

 

ok you guys have an idea of what target afr's i should do under each load. i know 14.7 is a good afr for idle and i think i wanna go to about 12.8 wot but what about the in between areas?

 

this is no turbo car ...13.8 would be more ideal... it all depends on the timing you add

 

13.8 sounds way too lean. all motor cars usually run 13 flat and turbos run low 12's or high 11's... if 13.8 was ideal at WOT then i wouldnt see an issue with 14.7 around town
