where can we get the progress springs and how much? the sprint ones are like $135 shipped on ebay.

One thing to never lose sight of, WOT is subjective at most with this car. You can have the pedal mashed to the floor and if the ECU says back off, it does. This is a MAJOR reason that "drive by wire" sucks.

shaneathan: It was under $180 from an eBay vendor, shipped.

Blu: Ah yes, good call. Forgot about the throttle-by-wire thing.

Why are progress better than sprint springs?

I wouldn't trust those A/F readings 100% either.

I saw your video, and they were using a tailpipe sniffer for the dyno, right? Those are never all that accurate. If you want 100% accuracy, they need to be using a wideband.

That was using a wideband O2 reader out of the tailpipe. It's pretty accurate.
