Paging Matt from Powerchip:

can you please explain/clear the MAF test results with and without MAFs?

Technically speaking, can the MAF test numbers we relied upon post MAF delete and powerchip mod?

higher l/hr numbers are the DME's response to the tune's air flow volume tables at the limiter? Anyone have any fuel trim data? Those might be a better metric.

If we see that everyone is running a little rich/lean in some conditions, what are the long term effects, if any?

Oh I and ordered my MAF-less tune today. Homemade IATS goes in tonight

I just scheduled the ///M to have it dyno'd Tuesday night. I will report 100% of the information provided to me.

I guess I could do some runs with the IATS plugged in then some with it unplugged?

On MAFs and on Alpha-N would be very interesting if you have the opportunity.

Do you have a dyno run from before the tune to compare to?

Matt, I'd like to proceed. I'v been trading emails with Paul Eriksson, should I order through him or work with you directly? Sorry but I cannot PM. Thank you, Gary

It would appear that everyone has been quite satisfied with the modification thus far. Besides a minor loss of mileage, has anyone noticed a drawback or down side to the upgrade?

Stopped by Powerchip today and met Matt, Matt, and Frank. Great guys. My tune was done in about 10 min while I chatted with Matt. I have to be careful not to get tickets now because it seems I am always in the powerband and the car is eager to go. I have not unplugged my MAFS yet, but I will soon to compare.
