Can completely draining the battery wipe a tune?
I had an issue of stuttering while cruising in 6th. It popped the light but now it gone. Ever since my car has lost a ton of snarl from the exhaust. It doesnt rumble or bark when snapping the throttle. I don't know how else to explain it but it sounds more stock-like now. Drivability funny as it may seem, seems to actually be better. Better low rpm pulling when lugging gears trying tosave gas. I got on it a couple of times and it pulls real had so mug that it might even be faster I dunno.
This is really wierd I can't believe the sound has changed, there's no service engine light on anymore either. I wonder if that jerking I was getting cruising in 6th may have damaged something ?
It all started with the driveline bucking while cruising at 80mph in 6th, it came and went. But the real change I'm describing here in sound and drivability only happened after I left the parking lights on and I killed the battery.
If reseting your battery makes the car drive better means your fueling needs to be tuned. The tune that you have now calls for shitty fueling, but reseting the battery fixes that...you need to get that fixed in the actual tune not by the battery.
