That's still on the table...ive just been disappointed. FBO minus fmic on pump gas i only dynoed at 335 rwhp/355 lb-ft. Underwhelming. I'm having some issues with the car and they might be hardware-related. Taking to the dealer soon. After that's sorted I'll try the procede again, but if it's not performing well then I'll try the JB4 for a few weeks. Just seems like people are putting down really impressive numbers with auto tune maps and E85 on the JB4. Procede requires a lot of fussing it seems and I don't have the time/knowledge to be constantly messing with this thing.
