Ported Intake Manifold

Because like andrew said , GPI always disables those codes so there isnt a problem i guess like i am having now, Smoke test showed absolutely no leaks and everything is as it should be installation wise , the only logical explanation is the tune was never right from the beginning and this intakes better airflow its throwing the codes! Seems pretty simple to me, and when iam out driving it and i clear the codes it runs pretty good! So i guess you can continue to question my ability to install a intake manifold if you want , but i assure you the plug is on right and hoses are hooked up and its not leaking!!!

I wasn’t questioning your ability, I was just offering things to look at that might be the problem and save you money for paying for a retune. I would have thought GPI would have mentioned the need to turn those codes off if you’re cammed in their product description. I’m going to ask my tuner if he turned those codes off.

There really is no way to cover all of the tuning changes that need to be made in a product description for a camshaft. It's not something unique to our product, any E38 ECM running a moderate sized aftermarket camshaft is typically going to struggle not to trip the P0106 and P0068 codes, and these are very standard to disable. They are not the cause the problems Bluebagger06 is having, but they are another indicator on the growing list of things that make us suspect that the tune on the car may be far from ideal, and likely is at the center of some of the running and driving problems he's having.

We've done everything we can to try to prove/disprove the manifold as part of the problem, and we've both concluded there is no observable defect. I've of course offered return/exchange if the part is believed to be the problem, but as we've worked to troubleshoot this we've not gathered information that really points in that direction, and I've come to understand that the tune-up has been less than desired well before the manifold was ever introduced.

To reiterate on another point, yes, we consider the ported rod-mod manifold to be a "no tune required" option. Because it's still the same runner length, almost identical plenum volume, same throat shape and size, and same resonance, it follows the exact same airflow curve and characteristics that the stock manifold will. I would assume that an obvious caveat here would be that the MAF curve (and VVE if still active) needs to be properly calibrated in the first place in order to just bolt on the manifold and go. It's also worth noted that in truly max-effort combinations there is always value in reviewing and touching up a calibration following any sort of change - but almost always there would be zero change with the ported rod-mod if the existing tune-up is accurate.

Bluebagger06 knows how to reach me, and that I'll keep working with him until he's got this sorted. I'm hopeful his local tuner can take another pass at the tune-up and cleanup some of the things previously overlooked, and bring this car into line. Truly it's awful to have a great combination of parts and not have them drive/perform like they are supposed to.

People often balk at the idea that we'd charge $650 for our remote tuning services - and I get how that can feel like a significant cost. When you consider the importance of the results the old phrase of "you get what you pay for" rings very true. We provide the absolute best tune-up you could hope for short of having the car in our own hands. It's not hard to get the fuel and spark dialed in for WOT performance, but we go so much further beyond that to make sure the driveability is maximized - cold/hot starts, idle quality and return, cruising behavior, shift schedules, etc - there are very few aspects of the calibration we don't touch to ensure the best possible overall result.

GPI didnt tune my car ,and are NOT the blame for my posts at all, A place that was on camaro 5 and has since been kicked off of here did the work and tuned it and at the time he didnt even know what GPI was, until i insisted on using there parts! I suspected all along the tune was just adequate enough and this intake just made it worse! I have put all new gaskets on the intake,including TB gasket, brand new hoses, smoke tested every , check plugs and wiring, new map,and maf sensors , so you tell me what am i missing ??

I do appreciate everyone's help!!

Brother man, I sad that you are having these issues with your Camaro!! I do hope that your tuner can get it all sorted out for you. It's gotta be in the tune you have currently, because everyone else who has ever installed the GPI rod modded intake with an aftermarket cam and extras, hasn't had any issues with it. Good luck, hope you get it sorted out!!

You’re didn’t missi anything. It’s just too bad GPI doesn’t mention in the product description that on cammed & tuned cars that if those codes weren’t tuned out that you might experience problems, it would have saved you a lot of effort and a few dollars. BTW my tuner said he turned off those codes in my tune when he installed my cam which was before I installed the ported rod mod

Once again a respectful and comprehensive reply! I can certainly understand not being able cover all tuning changes associated with a cammed car, but I think it would be useful to mention in the product description the likelihood of experiencing those codes if they weren’t tuned out, as well as mentioning a retune is not necessarily required for all the very good reasons you stated in your post …might also save a lot of a calls to Tech Support as well LOL

Thanks man, It sucks to have to mess with this but i will get it figured out. I decided to order HP Tuner and got a new laptop coming tomorrow to start to do my own stuff. But as my luck would have it GPI says the Module is back ordered!! I was like WTF!!Trying to see how long they will be backordered since it seems lot of places have them in stock!

Well it just goes to show you the differences in tuners, Mine didnt tune the codes out and probably not that great of a tuner so i decided i going to just avoid him all together. Yours did tune yours out so probably knows WTH he is doing! I would assume most tuners like yours know to tune the codes out to avoid issues!

New tune in from GPI , Did some data logging tonight and car runs like a dream!!No codes or stabilitrak issues!! Now for Ben to work his magic and fine tune this tune he sent!

This is what I love to hear!

Good news, your tune must have been right on the edge, bolted mine on and it ran great with a noticable midrange difference. I do want to get mine Dyno tuned.
