Default Lean Condition - Diagnosed

Since my last tune I have several times had lean codes pop up. I decided to have it checked and sure enough we found that the air bridge was cracked, thereby triggering the leanness.

I thought about replacing the air bridge with a nice CF decorative one but if i am going to do a blower soon then that would be a waste. So, we just resealed the crack in the air bridge and she's going back on the dyno today. This may explain why I was on the short side of the power range given the parts installed. I might have found the reason and some newfound free HP as well.

We shall see...

Assuming you were getting codess P0171 and P0174, the culprit can also be the MAF being dirty.

Yes, good call, I suppose it easily could. I will check that too.
