well if my defi gauge is highly more accurate, and gets similar readings, i'd assume it'd help clarify the issue at hand.

 

if i'm not mistaken the factory guage reads in kg/cm^2, not BAR. it's a minimal difference but a difference non the less.

 

Please read my post above, I picked up 4 PSI with a 10MM wrench and it did NOT involve a MBC.

 

+1. the first time i did a boost leak test i was like HOLY S%$T! at least 3 leaks including a torn vacuum line.

 

Thanks for the input, I had no idea RS's come with the same gauges, I dont get why GSR's dont

 

time to get an aftermarket boost gauge put in then lol. i guess mine's faulty because it almost reaches 1.5

 

Trust me that 6th gear... makes a diffrence

 

i only hit 1.1 kg/cm^2 on my stock IX MR.

 

when i got my ix MR back in march, boost would spike to 1.4-1.5 bar. about two months ago, my ix is boosting to 1.2-1.3 bar. i just changed the clamps to t-bolts and still gettin 1.3 bars. bosst never drops below 1.1 bar.

i have 5470 miles and the only mod i have done is a works drop in filter. so far, no cel's.

 

same

 

Umm... I'm sorry I was not aware that evo 9 RS's come with the same gauges. In fact I would like to hear from other RS owners if this is true, because I've never heard of them coming with a "cool 5spd aluminum shift knob" either...

And just like Max-Q said, I included only factory boost gauges because that is what I have. Its common knowledge that some boost gauges read differently than others, and there is much room for error. Your gauge reads in PSI, mine in BAR (or kg/cm^2 whatever it is). I'm not trying to glorify MR's or anything like that, just trying to get accurate information.

Is that peak boost? If thats the maximum boost you see on your stock IX then something might be up. I'm only hitting 1.2-1.3 but 1.1 is really low.

pm'd

 

Both are included in the optional RS Package.

 

guess ya learn something new every day Was this true for '05 as well?

 

I'm peaking at 1.4 bar (20 - 21PSI) then tapering down to 1.1 to 1.3BAR (17 - 19 PSI) I have hit 1.5Bar once on a cold morning (21.75 - 22.14PSI depending on your math) So I think it is totally normal.

 

Yeah that sounds perfectly normal, especially on a clod night/day. I have an 05 MR...all the mods in my sig. And i just installed a greddy electronic boost guage, and i still have the factory one hooked up. The factory guage is no where near as reasponsive to boost as the greddy unit. But when i installed the greddy i did a 2nd gear pull and hit 25psi and held right around 18 to 19 psi. And thats with no tune, and no boost controller. Needless to say on pump gas that NO GOOD!
