How much boost should i see

[markw351]

I am running the below mods and am only seeing 13lbs of boost. i recently installed the ported blower with the same size 2.93 pulley. looked like it was making about the same boost (11.5-12lbs). It has been 95+ degrees since the 2.76 was installed but still thought i should be at least 14lbs. I'm not seeing boost dropping so i don't think the belt is slipping. I did gain 1lb of boost from the 2.93. Does this sound about right with the heat and free flowing exhaust. No dyno numbers.
Steggy Stage IV
stage II ported T/B
cut/ported/welded plenum
2.76 Billetflow ultra-grip pulley
4 piece idler set
metco tensioner
JTL RAI
1 3/4 full full length headers
O/R x-pipe
steeda/borla catback

you loose boost with headers. how much hp are you making? should be in the 500's

no dyno #s yet, but i don't think i'm at 500 to the wheels. Kansas only has 91 octane so timing is set at 18* AFR is 11.5-11.9. my guess is closer to 485-490. I know i could add a couple more degrees of timing but i'm just playing it safe right now.
