My dealer told me I would never get more than 10psi boost at this altitude (Colorado) is he right or just don't want to check my car for a problem? I only have ever gotten 10psi since i've owned it. Is this because I'm a mile high or is my dealer higher? ~

 

Tell youe dealer that you took your car on a trip to somewhere that was sea level, and when you where there you unpluged the battery to reset the ECU and it still is not right.

 

Hmm. I don't know. it ccould be possible to lose 2psi of boost at coclorado altitude. I'm at 1200ft. where i live, and I only get 11-11.5

 

yes that is the explination, there is no problem. dont lie and have them check out your car unless you like to drop off your car, not have it for a couple of days and then get it back with absolutly nothing gained. i dont know, maybe thats how you get your kicks. its up to you.

 

Yes I am at about 5400-5500 ft. Depending on how spirited I am driving I get between 7.5-10psi. Nothing really above 5psi when just cruising

 

The Dyno will be the only way to truely tell if there is a lack of power compared to the "Normal" performance...

 

I am a 7000ft and when i put the interceptor guage in it showed i was getting 6.5 max in third while my stock said it was getting 10. I got the 3" pulley on now and get 10 when its warm and 11 when its cold. The 2.8" should get me up to 12, but the a super charger is not like a turbo, it doesn't create tons of extra boost so you going to lose some at altitude. What altitude are you at?

EDIT: saw you were a mile high so when i am in albuquerque i was getting 8 or so PSI stock which is probably close to your PSI that you are getting now. With the 3" i get very close to 12 but i don't think i have actually gotten it yet.

 

i was only getting 10psi as well i dropped to a 3.1 and now i get 12 - 12.5 most of the time now. drop me a line if you need any help or so.
