is this right? i have the 2.8 and im hittin 20lbs of boost....?

mods:

stage 2
2.8
injen
zzp tensioner
exhaust

those are the only mods that would boost me more

heres the video of it on my myspace.. kinda hard to see but here is it..

http://vids.myspace.com/index.cfm?fu...deoid=54434943

 

i had a 2.7with meth and was hitting 19.5

 

stock catback?
stock exhaust manifold?
stock dp w/ craptastic CAT?

Any cooling mods? increased PSI can be caused by excessive IAT2.

 

Either you are driving in extremely cold weather or your cat is starting to crap out on you. Keep an eye on it for the meantime in case the boost goes up higher.

 

exhauist wise its just the gmpp cat back..it just started doing to today on the way to the car show haha

 

clogged cat most likely.. or the starting phases of it.

You have any method of monitoring your IAT2s?

Recommend you do not go into WOT

 

plus our mechanical boost guage is crap

 

another possibility

 

its electronic, right?

 

my boost gauge says im boosting 17ish but dont know if its right or not

 

Maybe hes hitting 20lb's of boost cause hes cars ******* dead sexy and he knows who to park next to at car shows

 

I was under the impression that our stock guages were hooked up via the ECM. I would assume that makes it electronic, considering it's not hooked up via a vacuum line like I've seen.

Either way... only boost I TRUST is what my Hptuners logging tells me.

 

i have a 2.7 and ran 20psi when i had a clogged cat andd in the cold then it blew soo

 

What kind of boost will you see on the gauge with a 2.8" and a full exhaust? When i say full exhaust i mean header, catless dp and catback.

 

your cat is becoming clogged

yea ours are electric stock..and i only trust a mechanical boost guage becuase its hooked directly through the system no computer or electronics needed...

 

HPT is seeing boost from the exact same place the gauge is, I don't see why everyone makes a big fuss out of the stock gauge.. Yeah, they burn out, but other than that they're fine.

doesn't matter if it would be more accurate (which it wouldn't be unless your sensor or gauge are malfunctioning)

the ECU is still going to see the same boost as it was before, the gauge changes nothing unless you're doing a custom tune

 

its either boost gauge or temp/alt. im boostin 17 on a 3inch pulley and id have to have a cat for it to be the cat so its not the cat

 

when its cold i have hit 17.5 psi with my 2.9

 

haha is this kevin?

ummmm.... what blew?

 

Im seeing 18psi with a 2.8 zzp header, 3" dp, and 2.5" catless exhaust...

 

You cant tell from the yellow SS/TC in my sig

 

first hand experiance. I ran stock can and 2.5 ark catback and one night it just decided to melt. i was hitting 20 lbs at like 4500rpms barely made it home and when i pulled in the drive way reved it up cause it sounded cool with the supercharger sputtering but any ways the radiator cap blew off. next day unbolted it completely melted the internals of the cat

 

My stock cat had a very short clogging phase before it blew right out One day high reading on the guage next day louder car
