Or contact mellon for a custom email flash and just retune it for winter and summer. I say don't turn the boost down tune for the cold weather and enjoy the added powa!!!

 

could the plugs also have something to do with the cold, because i gapped mine smaller and it stopped cutting out?

 

well if you are flowing more air then the gap needs to be closer so you dont get spark blow out.

 

Well, Until I get the FMIC and New turbo I won't get a dyno tune yet.

Ivey or CBRD hopefully, if they will tune a 200,000 mile Evo....

 

I would never put money into a car with 200k miles on it.

 

Miles mean nothing. All that matters is how the car was maintained and the current condition of it. I've seen 100k mile cars in far better shape than 10k mile cars.

 

Yeah, I just brought the gap to .030 on the NGK BPR7EIX.

I cranked the boost back up and drove the sh*t out of it and did some 3rd gear pulls.
Logs seem to be okay. And now it doesn't break up anymore.


In the summer I am going to go with the colder heat range BPR8EIX with the bigger turbo.

I just wanted to say thanks guys.

 

Can cold air cause lean afr's? At the same boost levels.

 

If your maf and IAT sensor are working properly and you didn't mess with any temp scaling tables, then your AFR shouldn't change with weather changes.

 

200k miles? jesus. pics of car?
