[mike000g]

can anyone tell me what is the normal vacuum reading on the ms3 07 ?i have a dashhawk and the vacuum reads -20.18 thru -20.98. mind you im in florida the temp is 85f.from what i was reading people say they have readings at -28.00 or so.so im assuming i have a leak somewhere or can it be normal? here is a list of my engine mods:
corksport downpipe
corksport testpipe
HKS catback
HKS bov
garrett fmic
CPE tpi and intake
TRZ rm:stiff as hell makes my mirrors shake like if i had a sound system lol

ps:is required for me to change my plugs at this point??????

Seems normal, I idle at 20-22 all day long and plugs not really needed.

i guess it seems different to me,what mods have u done?

i see mostly in the 20.xx range, might hit 19.9x or 19.8x

Dude, 20 inches is fine on ANYTHING. Think man, it's pulling that hard at about 700 rpm, all is well.

28 you'll only maybe see on a high speed decel and that's just cause it's maxing the gauge.

the reason why i ask,is that with trz rm on idle i get this vibration thats on an off,like 5 secs apart,is like its really quiet one sec then my interior vibrates with the engine.thats why im asking if its normal.my rpms reads at 745 to 755.im gonna have to make a video.

vibes from an upgraded motor mount are expected, and normal. I changed my idle rpms to 975 with the accessport and it has elimited 90% of the buzzes and noises. Every once in a while I get some buzzing, mostly with the ac on. I wouldn't stress out about it.

i guess thats a sign to buy an accessport,my car is fully bolted.is cobb the only unit that lets you adjust the idle?
