pick up a new SAFC on ebay for like 265.. thats how much i paid for a new one... will make a big diff in the fc department... and as for boost... peaking at 26.. they are a lil to outside the safe zone for the mods... dial yours in to peak at 21 and stay at 21... unless you run some race gas or alky dont try going north of that... with the alky i can peak it at 26 , 28 if i wanna push it..

The difference is they have intake and exhuast. Has anyone else experienced this in Colorado? Is the key to raising your boost adding intake, exhaust, both, or something else? I have a Utec, but was going to wait until Dynoflash comes out to put it in. I was thinking I could raise the fuel cut point as long as I wasn't running lean. Any help would be greatly appreciated.

yes thier is one guy locally that runs like 29 stock headstuds.... which is completly worthless due to the fact that.... after 25 psi u are completly out of the stock turbo's efficency range.. and are just blowing hot air and will just make less power..

Id say the guy at 29 has a faulty guage considering one ( like mentioned above) its out of the efficientcy range and two its not possible considering you can only hit 28.... in the stock turbo ...
I know a guy here in colorado who on a completely stock Evo ran a 14.1. He had a great 60ft time too. i think a 1.6 or 1.7. So a high 13 in colorado is doable on stock Evo, but you better be a damn good driver.

I think elevation plays a major role on the Evo. I could only hit 19PSI at a track in Nevada at about 4000'. When I got back home (around 250' above sea level) I was hitting my normal 22 PSI. I could only run a 13.4 that day.
