Regardless of anyone's opinions of the situation, the LTG MAF & factory calibration is extremely sensitive to certain changes, and CELs have been thrown on catch cans, removing the silencer in the stock intake tube, intakes, a TB swap, and bone stock LTGs even have history of throwing codes for fuel trim out of spec due to excessive idling (per GM technical database via my dealer). |

Hey Guys,
Just wanted to chime in on the issue. This is the first we're hearing of any sort of issue with these hoses, but we are more than happy to look into the issue to determine a path forward. To start I would like to say that there has been significant R&D performed for this product, which included creating 3 different designs and testing with airflow calculations and on our flow bench. We also logged plenty of miles on our Camaro between testing this hose and our intake system, and I can assure everyone that the factory MAF housing wasn't altered in any way for this product. And as always, for more information on any of our products in the R&D process, make sure you take a look at our Engineering Blog. For reference, here's the four stages of our induction hose: That being said, it's hard to tell how any two-three aftermarket components will react together, especially when it comes to changing the cat or removing it all together (even our catted dp requires a tune to ward off unwanted CELS). I notice that both of the issues are coming from the combination of the intake tube and an aftermarket downpipe, which we didn't have issues running that combo on our Camaro, but it's something that we are more than willing to look into Quote:
Just wanted to ask a few questions to help narrow down what's going on. Are you getting these backfires while you're on or off throttle? Also, I was wondering what you had on your car when you got your tuning, and if you had it adjusted for the induction hose? There's a chance that it might not be compensating for the additional airflow and is slowing the timing. Quote:

Just curious about what other mods you’re running? Are you still on the stock tune? Also, which downpipe are you running? -Nick Last edited by Mishimoto; 11-10-2017 at 02:39 PM. |

Just make sure you guys let us know of any issues that come up in the mean time! Quote:
I'm actually about to update that thread as well, check it out in a few Also we do offer drain kits for the catch cans to take the struggle out of servicing the cans -Nick |

Took off the mishimoto intake tube and my trouble went away. Got two different codes, idled crazy rich and had many mid-exhaust backfires while coming to a stop and when slowing at part throttle. Bad tube? Need to tune for it? Waste of money?

Hello Everyone
Mishimoto actually does do quite a bit of R&D on every product prior to release. If you'd like to learn more about this product, in particular, feel free to check out our engineering blog showing everything we discovered along the way. https://www.mishimoto.com/engineerin...e-intake-2016/ You could also take a look at our engineering report showing all the numbers and specifics on the final product. https://cdn.mishimoto.com/media/prod...ringReport.pdf Feel free to reach out directly if you ever have questions or concerns at support@mishimoto.com or 302.762.4501. Ext 2 for customer service. Thanks -Jake |

What were the codes you were getting? I just want to make sure that I'm interpreting correctly, you're hearing crackles and warbles as soon as you let off the throttle? So for instance, if you mash the throttle, get to speed, and the let off, once you're letting off is when you're hearing the backfires? Also, we designed this tube to run on the stock tune, I noticed that you do have an aftermarket tune on your Camaro which is calibrated for everything that was already installed, but not for the added airflow when you installed our induction hose which could cause some issues. I would definitely recommend reaching out to your tuner (once he's back in town) to get an update on the reprogramming. As for the PCV connection on our hose, we kept with GM's direct fit connections for our catch can kit and the fitting on the hose, so I would just make sure that your factory hose is latched down securely on that. Hey Lauren, I'll run this back with the Engineering team. This is the first we're seeing of any codes through our testing and from other customers. Like I said above this is designed to run on the stock tune, so it shouldn't be throwing a code. There's a chance that the two together could be throwing something off. I did see that you were looking into a tune, I would be interested to see the results from that. -Nick |

P015b got this one 3X, initially had a P207?? right after install which I cleared and had not returned. No , not crackle and warble? What I am getting is little explosions that feel like they are right underneath my seat when decelerating, doesn't matter where the throttle was prior to slowing down. am wondering about your return policy now cause I am not at all happy with this product! I have the mishi dual catch can setup so if there is a bad connection there it's on you. and I get the same results when I went back to the stock tune

Hey Rick, What I'm suggesting is not to return to your stock tune, but rather update your current tune to include the larger induction hose. Your current tune is specifically calibrated to the parts you had installed at the time. Changing parts afterwards, especially intake and/or exhaust components after without incorporating them into your custom tune could result in issues like these. If you're still interested in a return I can set you up with one of our customer service reps, but I would suggest getting in contact with your tuner first. -Nick |

I think my favorite part of the 'engineering' paper is where they extol the benefits of using a plastic MAF housing due to it's superior heat rejection, but then you made the box out of sheet metal because it's SIGNIFICANTLY cheaper. I know what it costs to set up a plastic injection mold. An airbox would run in the $10k-15k range. I was quoted $5k setup and a minimum 1k run to mold the lid I wanted for my 4th gen back in 2005.

I was quoted $10k for a single piece for a cold air intake I was making for the SS back in 2011/12... Shits not cheap. Although it would have dropped my part cost from about $180/ea down to about $10 ea. I would have to run 500pcs minimum per order. |
