[QUOTE="91svtbird, post: 9894284, member: 37026"] All due respect Jeff but I see that you already had a custom VPM tune with and aftermarket C&L mass air meter which means that the mass air transfer functions were changed as well as other parameters. So how can you say that the L&M needed a tune when you were not using stock Ford settings to begin with but instead relying on a tune that had already been changed to who knows what parameters. Any car that has an aftermarket SCT tune in it will in most cases have enough changes made to it to cause problems when a TB is swapped out especially if that tuner uses short term fuel trims to alter the mass air transfer functions. Another thing that is often tamperd with by the "well known" SCT tuners is the driver demand tables. This will definetly have an adverse affect on proper TB oppertion. [/QUOTE]
