Boost Change
Temp/barmometric pressure makes a decent sized difference with a s/c.
As observed with my car, the gauge has a recall and is very repeatable since I shift with a shiftlight.
I was seeing 8.5lbs when it was 50 degrees with a 30.4 baro (7.09 @ 98 at 2000' DA)
7-7.5psi when itwas 85 with a 30.2 baro (7.23 @ 97 1/8 - 11.27 @ 122 1/4 1500' DA)
- 10.96 @ 124 1/4 500' DA)
Three different tracks so its hard to go by ET/mph but the boost gauge doesnt lie..

My old car was a turbo MR2 and it would change by about 2 psi between day and night. Roughly 40-50 degrees air temp change. It had a HKS boost controller on it. My SC'd WS6 notices altitude more than temp. I pick up about 2 lbs. at sea level. I'm at 4500' normally.

When i first got my car i was seeing 8lbs for the first two weeks... Now i only see 6lbs... The weather is the same.... I changed my blower oil last night and i didn't see any belt dust and the belt seems to be tight enough... Should i tighten the belt a little more and try a smaller pulley...Cause my car is tuned for 8lbs and i really want to see the full 8lbs... Although when i ask speed inc they told me not to tighten the belt anymore....What would you guys suggest????
