I was curious as to what program you guys are using for tuning ?
I'm using HP tuners and was looking for someone that was also using it and has a setup very similar to mine. Or if someone wouldn't mind looking mine over for anything that might not be set right. I'm waiting on my wideband to come in so i can closer dial in the fueling because as of right now i'm getting about 12mpg in town and about 18mpg highway.

sounds like your running rich, but I get only marginally better efficiency with my GT, it can have alot to do with the weather

I wish I could help you on this one Kent. There are a hand full of turbo guys on here, but I dont see a lot of chat from them.

It whines a lot, but I like it.

The only limitation you will ever face in life is yourself!

I have a turbo, and HPT....but have yet to use both....

weather is a HUGE part in fuel economy right now!! I have gone from 19-20mpg, down to 11-13mpg...and this is with me running an AFC a bit on the lean side...

so no one knows specifically what to tune for on a turbo build? like how tune differs from a NA, SC'd tune?

I haven't really ran into any issues yet. Other than the fact that my car won't shift from 1st to 2nd WOT.
