Ebay'd a 15437 Volant CAI for $180
Not crazy about the oiled filter that comes with it b/c I've seen them mess with sensors
Had to trim the main tube a bit to make it fit, otherwise no problem
Clean my MAF/IAT sensor
Sounds awesome
Nice power gain
...until
the next power cycle I get a CEL
Notable power drop and hesitation at WOT
Go to O'reillys and pull the P101 code
Push through it for a couple of days for daily drive to work
Get 17mpg as opposed to my stock intake getting +20mpg :th_crazy:
Replaced my stock intake and the CEL hasn't happened yet

Probably going tomorrow to a local tuner to see if I can get a proper tune and maybe remove the 100mph governor

Should I install the Volant before I go to the tuner or just take it with me?

Thoughts, suggestions, previous experiences

Sounds like you're having all sorts of problems...imo I would put the intake back on and then get it tuned :shrug:

What did you clean the MAF with?

P0101 - Mass Air Flow (MAF) Sensor Performance
P1101 - Actual measured airflow from MAF, MAP, EGR, and TP is not within range of the calculated airflow

I'm probably going to at least take it and my tools with me when I go to tune it

Not a problem to install now that it's trimmed properly

Any suggestions for what to tell the tuner?
All I know is that I want it to accept the new CAI and remove governor
I know tunes gain power but idk anything about the specifics
Don't want too much power and loose mileage, and vise versa

I used CFC brand MAF cleaner

to quote my chilton manual
"P101 Mass air flow or volume problem, IAT, MAF, or MAP"

like I said, it went away when I replaced the stock intake

You did burst shots of the MAF cleaner right? You didn't overly saturate or touch any of the wires or sensors with your fingers or sprayer straw?

I would put it back on and check the intake, fittings and vacuum lines for cracks / leaks. Also Pull the negative battery cable for at least 30 min. before taking it for a test drive.

I would put the intake on the truck when you go to get the tune, just let the tuner the issue your having. Bring your stock intake and tools with you just incase.

lol yes I read the label on the can before using it

If I tune it then decide to get more mods later (like a cat delete or muffler) will I have to tune it again?

Yes it will need to be tuned again in order for the computer to "learn" the new modifications

I checked pretty well for leaks, all short of lighting a cigar and watching for vacuum holes.
I pulled the battery to clear the CEL, but it came back, twice.

I might put the CAI on tomorrow morning before I head to the tuner.
I just hope they're open on Good Friday.

Tuner can turn off the code for your cat delete if you decide to do it later, muffler you will need to get it retuned.

Where you getting your tune done at and how much? Is it a street tune or dyno tune?

I'm going to Complete Performance in Jasper TX

Not sure how in depth they are, or even what I'm in for. I don't expect more than street tune.

My dads BDay is coming up and he's got mods for his Duramax without a tune, so I figured while I was getting his tuned I could get mine done as well. He's been wanting to do one since his cat delete and CAI a few months ago, but didn't have the money.

Alright not to steal any threads here but the tuner can remove the CEL code after gutting the cat? Mine popped up :shrug:

Update: Replaced stock intake and went from 17mpg up to 22mpg
Tuners weren't available all weekend.
Called them this morning and the guy says that the only thing he can get for the 2.9l is a jet PCM chip, probably something like:
2007-2008 Chevrolet Colorado Performance Module and Chip Jet Performance, Jet Performance Stage 1, 49-state legal - no CA shipments, Direct fit

He says he doesn't think it'll fix my CEL though.
I'm gonna take it to them tomorrow to see if maybe I did something wrong hooking up the CAI and ask him if maybe I need a better MAF/IAT like:
http://www.carparts.com/details/Che...ncej20691431&gclid=CLjhoJnYqbYCFQuCnQoduWEAzQ

I'm really disappointed though. I was thinking these guys would be able to actually TUNE my truck rather than just put in a dinky little chip.
I want it to run right and haul ass without the top end limit.
I guess I can look into one of those diablo tuners like:
DiabloSport® DBLI1000 - Chevy Colorado 2008-2011 inTune Programmer

I'm open to suggestions.

I wish I could find a tuner using hptuner in my area.
I was hoping that this guy was doing it since it's a pretty legit tune shop.

They can tune a 4 cylinder, also chips are worthless. I don't know much about running but I'm sure somebody will have more knowledge on this subject

Decided to put the CAI back on today before going to tune shop tomorrow.
Cleaned the MAF/IAT again and tried to make sure it was sealed up better.
Ran great for 3 engine cycles.
Went to O'reillys to get the codes read and I got the same P0101 along with a new code:
P0171 System too lean (bank 1)
I'm thinking it's either because the impedance of the stock MAF is too low or maybe because of the oil in the new filter.
I think the impedance is too low due to the P0171, but the P0101 makes me wonder if it's the oiled filter, especially since it waited until a 3rd engine cycle to come up.

I don't know if I should get a high flow MAF or a different filter

TL;DR Help, I am confus

Maybe the guys at the shop I'm going to tomorrow will have a smoke machine or something to check for leaks and/or offer suggestions to fix it since they don't have a decent tuner. If this doesn't work out then I have the name of a tuner in Beaumont, but he usually does racecars so idk if he'd help me.

Just got back from Custom Performance.
I pretty much paid a guy $20 to tighten the MAF screws and tell me that it's fucked. I was waiting for him to strip the screws out and owe me a new CAI. He cleared the codes for me, and the engine stumbled trying to get up to highway speed on my way home. I decided to go home and put some RTV under the gasket to try and seal it up.
I'm gonna call Volant tomorrow and see if they have some kind of adapter plate. If not then I may just make one myself.
