Holley Avenger?

[S10xGN]

Anybody thought about trying one? IIRC, the ECU can be had for around $900...

It doesn't look too bad, but who makes a plug and play interface for the buicks?

Haven't seen one (nor any CAL maps) but the wiring on these cars is relatively simple. Prolly any J/Y harness from a GM injected V6 would have the right connectors, then just a matter of running them to the proper pins on the ECU. I'm checking out their tuning software right now...

If you need a gm ecm header with soldering pin board I have a few spares.
