TPI Batch Firing ??

[Fast355]

Good to hear. Hope it continues to work as smoothly as reported now.

A 2bbl feeds 2 cylinders on each bank from each bore. Some of the TBI manifolds (Edelbrock 3704, GM performance, stock L31 TBI and marine TBI L31) and carb manifolds used with TBI have the cylinders and TBI bores feeding them swapped in relation to the OE TBI.manifold. I swap the injector outputs at the ECM on engines using those revised manifolds.
