[QUOTE="Willie, post: 16692488, member: 14133"] I had this TB years ago, actually both the L&M 66 and 72. They used to advertise no tune required, so I tested this "fact". Indeed, both ran well with stock TB calibrations, which I was happy about because back then, I knew nothing about tuning TBs. Years later, I came across an Effective Area data for the 72mm>> [ATTACH type="full" alt="L&M 72mm TB Effective Throttle Area.jpg"]1727229[/ATTACH] Being how my car ran fine with stock calibrations, I did not know what to expect by changing the above, but I tried it. Please note to your tuner that any changes in this table should be in conjunction with changes in the FF TA Prediction Angle table. It is basically an inverse of the numbers above. If your tuner knows his stuff, he will already know this... Just throwing it out there for you, as knowledge is power! Anyways, I made these changes and my car ran no better or worse. Datalogs showed no significant changes, so I'm really at a loss on why. My recommendation is to copy the above table and try it. [/QUOTE]
