My impressions of running stacked. Thrilled and scared. (disclaimer, stock injectors and fuel rail with Pierburg SL55 pump) The boost and instant power in the midrange was impressive. Then I noticed the 14.7 AFR's at part throttle along with that huge boost. Danger Will Robinson! At the track the car pulled crazy hard until 3rd. gear then it laid down. Don't know why. AFR's were around 13 in 3rd. which may be the answer. If you got the fuel figured out, as it appears you have, you should be golden. (11.8 IMO) Good luck with getting traction. (my problem)

I haven't run stacked since. Only did it once. Perhaps I'll do it again and put my car on the dyno.

I'm really interested in the mph in the 1/4 for your car. The most relevant number of them all for me.
