anyone else having fitment problems with their Halltech Stinger?
My guess is that the bridge was cut too short to begin with. That is the only explaination for your problems. We have 200 C6 Stingers on the road, and you and Jimman seem to be the only ones with this fitment problem, so lets fix it.
What I cannot understand is why folks post these problems on the forums before ever contacting us? We are easy to reach, easy to deal with, and I answer my email 12 times a day, and I would be happy to refund you in full if you are not satified. What could be easier than that?

As far as power increases, well today will be the first time i actually drive it. It looks like it will flow way, way better than the stock set up so im sure there is HP to be gained. I just wish either 1.) the air bridge would be bent an more of an angle or 2.) the silicone coupler would have an angle put into it or at least be flexible (accordian style like the stock piece) allowing you to get the perfect needed angle to make everything line up with no gaps anywhere. And just to clarify, when i say gaps around the bandclamp areas i dont actually mean "open" gaps that leak air but gaps as in both pieces are not mating up in a straight line.
any comments, ideas???





The Callaway is a very nice design, made by very nice folks.
It must kill you to have to tune cars with our intake onboard.

Our Stinger will never cause the car to run lean as long as you use the stock C6 MAF sensor with the laminar airflow honeycomb screen.
WOT, however will not reset itself since it is a preset table based on Power Enrichment/vs. RPM. This is Open Loop. Open loop has no connection whatsoever with the O2 sensors and takes its cue from the PE/RPM table exclusively.
There is some dispute about this, but I guarantee that it works as I have described. I spoke to the GM programming guru Dave Halett that dials in each new Corvette and designs the programs for all the vettes. He told me that there is NO connection between Long Term Trims and WOT, and there hasn't been one since the GEN III engines.
He told me that the reason additional fuel ends up on the dyno pulls is a direct result of countermeasures GM has in place to protect the cats called COTP. Shutting off COTP effectively disconnects the ECMs ability to add more fuel than the PE/RPM code prescribes. We have all seen this happen, especially on the C6, which is much more aggressive in protecting the cats.
Both heat, water temps, and load affect the COTP circuit, and there are three fuel enrichment circuits to either dial up or dial out altogether.
Recently I saw a dyno of a C6 6.6 L Stroker, with headers, cam, ported heads, HF cats, X, and Bassani exhaust, BBK intake making only 398 RWHP.
The LT Trims were around zero, but the a/f ratio was below 10:1 on the dyno. How could this be if the LTFs affected the WOT fuel cell? Well it doesn't. Most LS2 Beta testers are taking the PE/RPM target air fuel ratio and duplicating that number for the COTP value. Big mistake. The COTP code is an add on code not a target value.
If I use say 13:1 target under PE/RPM, and turn the COTP off, the LTFs make absolutely no difference on the dyno. I get a 13:1 air fuel ratio.
Check this out. I have proven that the LTFs make no difference on the dyno>
During our initial testing of the LS2 C6 Stinger, some might remember that our MAF up front got crappy results, but that was due to the COTP circuit kicking in. Our first dyno pull on two different dynos showed below 10:1 air fuel ratio on the first pull. When we reinstalled the stock intake, the air fuel ratio instantly jumped to 13.2:1 and settled at 12.25:1 at 6200 rpm, which is exactly what the PE/RPM code prescribes. We put the Stinger back on and instantly the air fuel ratio went back to 10:1.
Now how could Long Term Trims have caused this instantaneous air fuel ratio change with the car sitting on the dyno the whole time? They didn't. The car was dynoed at first with the water temps at 225 degrees for the first pull. A half hour went by before the stock pull, water temps and engine temps had dropped below 170.
Hope this helps.

The fitment question is really not a Stinger problem, but rather the nature of the C6 intake tract. If you look at the stock bellows and measure the angle GM has from the factory, you can see that there is a very steep angle from the MAF to the Throttle Body. They do not line up at all from the factory.

The Halltech Stinger all but eliminates the angle of approach to the throttle body, which provides a straight shot from the end of the MAF to the throttle body. The stock bellows creates a bigtime turbulence problem right before the throttle body, which is one of the reasons the Stinger SSM kicks the competition's arz on the dyno:

The knotch: This is purely a cosmetic deal, that actually pushes the whole Stinger closer to the TB, but raises the filter by 1/8" from its set position. We are now putting a knotch in the new connection hoses going out, but I do not recommend sliding the unit out of its original position. We have sold over 300 units and only a couple of folks have complained about the install. www.CorvetteC6.com
We spent 1 month and had 6 different filter sizes in our R&D to keep the overall size of the unit perfect. 1/8" may not sound like much, but we recommend you do not use the knotch when putting the unit together.
If you view our installation video, you can plainly see the Stinger goes on the C6 in 5 minutes.
Installation TIP: I put the connector hose on the throttle body without the hose clamps on at all. After I install the MAF into the connector hose, I install each hose clamp, and tighten them one by one.
There will always be a slight downward slope due to GM's position of the MAF in relationship to the throttle body.
We eliminate this slope except for maybe 2 degrees. The Stinger can be adjusted to slope slightly and still look perfect on the car.
