Please take all of us 4.10er advice and join the crew, 4.10's, 4.10's, 4.10's. You will be happy, I can almost garentee you this. I had 3.73's before and always kicked myself for not getting 4.10's. Now that I got 4.10, I will never go back unless I get a poweradder.
as asked, i dont know your definition of expensive. as much as i cant believe im saying it, ahhh, Shtty is right. blow the thing, at your altitude. used blowers are not super pricey and are great for oxygen deficient places.
guys, im not a nitrous guy - but since it is a catalyst, would it help him at the track (making up for a lack of O2)? i think it would.
