Realize this is an old thread but also wanted to prevent the 'did you even search' response....
Is this the clutch delay valve getting in the way the rev matching?
I have another car (higher redline I4) with an ECUTek tune that implements rev matching and frankly the Supra's always seems late...
Brought home a final edition this past week, am new-ish to the CLT area and curious if there are any recommendations for ceramic installers in the area.
TIA
