Tuning for altitude

One thing I found out a week or so ago is be prepared to turn your fuel pressure down. I ran at Boise with both cars, same fuel and ignition systems and the Stocker Ran good the Superstock was 3 tenths slow. I chased my tail changing everything I could and a good friend I texted said lower the fuel pressure. I did and my 60 foot went from 1.35 to 1.26. Both cars run the same carbs, same fuel pressure but obviously the Superstocker is more sensitive due to the power level. I have passed this along to as many as I can.
