My turbo doesn't seem to spool up as much as it should but I'm not getting any check engine lights. Any ideas?

With the lack of information you've given, we cannot help you.

Mods? Boost gauge and readings?

I have an intake and a catback. It seems to spool fine it just doesn't go as high on the boost gauge. I just noticed it started doing this the other day

As high as it used to on the boost gauge. It is not tuned, do you need one with just an intake and cat back? It's a Perrin intake.

You need a tune with an intake.

And why do you not give us information if you want the help?

How high is as high as it used to on the boost gauge? (In PSI or MPA if stock gauge) And how high does it go now?

Seriously, give us information or you get no help. We don't know what gauge you have, how it's hooked up, what it reads in, or what it used to even read.

It's the stock boost gauge it used to red closer to .05mpa now it's around .025. The intake I got said it was tuned for car

All intakes for these cars say they are "tuned for the vehicle" but if you had done your research, you'd see that intakes need tunes.

.025 is only 3 psi and physically almost impossible. Why? Because wastegate/default boost pressure is 7 psi. .05 MPA is also bad, as that IS 7 psi and only wastegate pressure. AKA you've been apparently running low boost for quite some time.

Check all of your hoses for cracks, replace as necessary. Also inspect your entire intake tract for evidence of a boost leak.

It is night here and I only had a flash light to look with. I didn't see anything but I noticed the inlet hose seemed to move quite a bit. I couldn't see under the intake manifold to see if it was loose or not. I will have to check further with day light. I have never had a problem with this intake before. I cant be 100% on boost gauge location as I usually watch the road, but I do remember it being a couple of lines above .05.

I do appreciate any help.

After going through and tightening clamps and cleaning the MAF it seemed fixed for a day as I had boost well past .05 MPA for a day. Now it has started up again. I was able to look a little more under the hood and noticed some foam and e-tape on a hose from the inlet tube under the intercooler. Is the foam something that should be there, does it come from the factory with foam there?

he is talking about the Y-pipe behind the intercooler. yes the foam and electrical tape is stock form. present in mine as well. You running an intake without an actual dyno tune is gonna cost ya. chances are you're running rich and hurting the motor. i bet your AFR isnt reading 14.5-14.7 at idle. either you take the cold air intake out and put the stock airbox back in ORRR get an accessport and install the right intake and flash for it. i would say that is to begin with to track down your boost issue.

I bet it is reading 14.5-14.7 at idle, but his AF learning value might be outside + / - 5%.

OP, do you have a friend with a tactrix cable or an AP (you do not need to install the AP to log values from your ECU)? If so, they can connect up to your car and see what your AF Learning A, B, C, and D values are. That will let us know if your intake needs a tune or not.

So me and a buddy traced the boost issue to a bad waste gate solenoid. It's on it's way so I'll fill you guys in after I install it. I have a Cobb ap but with the readings we saw it ran better without the Cobb flash. I am looking into getting a real tune after I figure this problem out.
