70mm tb's dont show any improvement unless you are making over 400 hp N/A.
Jimberg- whats this about the computer using tables it has built at W.O.T? I thought open loop was all preprogrammed.
And I have heads, intake, cam, etc...and my car runs much better on the lean side, like 35 psi. Dont know why you all run better richer? Maybe running a cooler water temp. has my computer trying to run it rich? I usually dont get over 180 degrees.
