So when I get home this weekend from a work trip my upgraded turbos from 4DR will be waiting for me. All-in-all plans are for turbos, downpipes, meth, and a dynotune at Livernois. Due to work scheduling I probably won't be able to get up to Michigan until first of the year.
I know I can toss on the upgraded turbos with no tuning issues but I might as well go ahead and change out the downpipes since they have to come off anyway. I'll be itching to go ahead and install these so I will get the PPE catted downpipes and put them on to.
Will adding the downpipes also cause any issues by running my current LMS 93 tune?
Nope, you'll be fine. No tune update required for downpipes. You'll just spool faster.
I will say that you guys that are throwing on mods that will probably tweak you to running a little lean without a tune adjustment are braver than I.

Nope, the car runs to commanded AFR UNTIL you run out of fuel. As long as you have capacity if you have tuned it for .78 lambda it will kill itself to hit that mark.
VERY smart ECU.
If for some reason you do start trending lean the car shuts the throttle body until it recovers AFR. My car should have blown up many times by now due to mishaps with the aux fuel system and being at WOT, the car should have gone lean, detonated and destroyed itself. It did not, not once, not twice 10's (maybe 100's) of times now.
With mild upgrades on pump gas it does a great job of making sure it is safe. If you have too much timing though, that can be an issue, not lean but timing.
What do you consider too much timing?

That is going to depend on allot of factors. Octane rating used in the vehicle, high or low temps can have a big swing effect. Altitude plays a roll, humidity.....the list goes on.

Better question....do you think the timing can get out of whack on a stock tune? I ask because I'm playing with E-85 and I'm seeing timing advance @WOT/full boost around 20-21 ish.
