Thread: Just completed my top swap..first test drive left mewith concers...

Here's how you tune a top swap.

1. Get a stock or canned GTP tune.

2. Put stock GT tranny tables in it.

3. Get a wideband.

Thats it. It SHOULD run well with that. Then start adjusting fueling with the wideband from there

Or since we can go straight to Will and have him do a custom in car tune.
