How about a Pro-Pipe that uses your existing 90mm MAF electronics making the new MAF diamter larger than 95mm. Check the classifieds. No codes for sure.

 

I know Swanson used to be a big fan of the Pro-M MAF and had a lot of experience tuning for them. You might want to give him a call and get his opinion since you have an autologic chip. He is great on the phone and will take time to answer your questions.
