Problem with the chip tuning is that it's not the typical type of tuning done for the engine. This is because of the Autothority MAF system you have installed. I'd consider getting a baselined 3.4L chip from SW, and install the old standby barn door air flow meter. SW knows the deal with the Autothority MAF. But I suspect you'd be better off with the original system because he's done MUCH more development & tuning on cars with the original system.
