Ok so first with the tune i had a/f problems i was running way to rich bout 10.8 well we fixed that problem....now im having problem with airflow this is what vince sent me....

Yes, looks like there is maybe an air restriction perhaps – I can see clearly in this log a point where boost is fluctuating and airflow stops climbing at 5000 RPM. I don’t know, man, probably one of the parts you installed. I might suggest removing the intake system and see how it does, we’ve seen lots of problems with aftermarket intakes on these cars.
In the log we see the airflow coming in is about 23.8 compared to others of 33.7

anyone else seeing or hearing of these problems?? any suggestions

 

Try going to your stock air box setup to see if it goes away.....Intakes have been an issue on these cars, especially the breather line.....

 

yeah im going to try that first....u have same tune...uve had no problems wih ur dejon intake?

 

i have the trifecta tune and yes you have to run the stock air box i also have a dejon cai and the car wont run right go back to stock

 

ok will do did u have any a/f problems?

 

That blows man These cars airflow sensors seem to be waaay to sensitive to proper placement and intake tube diameter which is why I just stuck with a drop-in filter, didn't want the headache. With my luck I'd have nothing but problems. Which kinda sucks because I like the way the intake makes the car sound.

It'll be interesting to see if GM lets you purchase the intake assembly that is supposed to come with the new stage kit separately, I'd be willing to try that out.

On another note I've had no issues with the tune so far, it's been on for about 2 months and 1600 miles or so, no cels or anything unusual. After my data log pulls when I first installed it Vince said no adjustments needed to be made and that A/F trims and everything else looked great. I haven't had it on a dyno yet nor have I logged it myself but it pulls the same as it did when I first installed it and it runs great.

 

That's why I'm back to the stock airbox too

 

Damn well I'm going back stock for sure if I'm lossing 50hp fro
this cuz I got dynod at 248whp and 312 tq which is bs

 

Definitely man, that's about the same WHP most of these cars put down stock... I bet you put the stock intake setup back on and make sure your breather hose is good and snug and you'll see an instant difference after the ECM re-adjusts. I'd do another datalog run if you still have Trifecta's gear and send it back to Vince so he can tweak stuff with the factory intake setup on. K&N drop-in FTW...actually not even that, FTLH (For The Least Hassle), lol.

 

dude this is pissin me off... i want an intake but i dont wanna throw cel's or **** up my trifecta tune when i get it... does the aem intake throw codes too?

 

I have the Dejon intake and have had no problems what so ever. I'm waiting on CIA though to come out with there SRI. There take their time and benchmark all their products.

 

yea but i would like a cold air... i dont really see the point of a short ram.. its taking even hotter air from the engine in... i would rather just put a K&N drop in in there... but thats jst my opinion

 

Hey, your good with a K&N drop in and the tune. People with those setup are getting 300+ so its not a bad step. You should read the benchmarks that Dan made with the SRI and how there was not a dfference between the CAI and the SRI. Also, think about it( and this in my opinion), So people are getting CAI for ths sole purpose of not routing the heat produced by the engine into the intake. Well, ok about that cold air that enters the CAI right to the turbo which is running what temp? 300 or so degrees. So your CAI didn't do much cause your air heated right up at the turbo. THis is why people have it mixed up and the real upgrade or even having one should be a intercooler as that truely helps cool your air entering the engine.

 

I'm running a K&N intake(no tune yet)-check out the airbox mod thread(LNF section)-apparently some gains can be made with stock airbox. Something tells me the GM "stage" intake won't be available seperately-just a guess

 

Actually I havent....but I've made sure not to have a leak at the breather hole (dejon redsign and then I have pressure seal tape (black) around the fitting to secure it). I like Terminators idea of just removing the fitting outright, and might eventually do down that road, but I'm waiting to see what GM comes out w/ on the stage kit (if it comes out)....Curious to see what the intake is. The stock intake has a horrible bend in it going from the box to the turbo.

If I was running stock box I would run stock filter. The job of a filter is very simple, stop dirt, there is little gain if any going to a drop in high performance filter (wasted money and puts mroe dirt into your engine). Intake kits are getting rid of the un-natural factory bend right before the turbo, and increasing the surface area of the filter (which means more flow)

Why don't you try and get a real custom tune. Not for nothing but it would be a lot easier to diagnose and fix your problem at the car than hundreds of miles away through e-mail. The fanboys of the trifecta tune will tell you otherwise but sometimes you actually have to go to someone who can see and feel you car.

 

whats the point of a CAI though? The turbo is just going to heat up the cold air when it compresses it, and then the IC will cool it off. So it really doesnt matter from what I understand.

 

yea i forgot bout that... i guess the better question would be which short ram doesn't throw codes then?

 

ok i put my stock intake back on and now it seems im running to rich again idk. At 5k rpm my car bucks a little and the boost flutters around. clogged cat??? bad tune...?

 

I noticed you have a CIA down pipe. This sucks but you could put your stock dp back on cuz it sounds like the cat may have been damaged from running so rich.

 

Do you have dashdaq or dashhawk?

I just find it odd that running rich for just a few days would cause the cat to clog. You had the tune only 1 week before it was dyno'd right? (dont you even have the catless setup)

Which leads to tune or something else...Do you have a 2ndry ECU? I would try it on the stock programming to see if your experiencing the same issue.

 

I told him to try his stock tune again to see how it runs if it still has misfire codes then that means something is wrong with his car. If it runs fine it is the tune.


No issues or retuning necessary with my Dejon SRI. MAF error was only 2% stock airbox had a 1% error so about the same as the stock air box as far as signal integrity, and added some HP up top that is for sure.

 

I have Dejon and havent had any codes at all, and its been on for over a month and 1000miles.

 

I guess that makes two of us.

 

i threw my stock ecu back in there and my car ran fine...its 10000000000% the tune
