It's been in and out of the engine about 10 times in 3 years, either to swap to a G and D for comparison, or just for maintenance. On each occasion I gently picked at the edge of the rubber pad just to check for bond integrity. Considering the extremes of temperature, moisture and oil vapour, not to mention 25-30psi boost flowing through it, it just seemed prudent to check it wasn't detaching.
The last couple of checks the bond had let go very slightly, but it didn't concern me at the time. The last check and what prompted this thread, the separation had spread drastically. Once that much air pressure gets under the slightest lift in the bond, well, we all know what tornados do to roofs!
Brett from GFB ('Go fast Brett' on youtube) came back to me and was extremely pleasant and civil about it. He said they improved their tooling and bonding process in 2014 and suggested mine was an older model that pre-dated the improvements. Mine is the only failure he's seen out in the field but alluded to it happening in testing prior to the 2014> changes. I wasn't seeking compensation or to kick up a big stink about it, merely to pass on some customer feedback and he was grateful for that
Anyway, that mega glue I used in my other thread seems to have done the trick, but please do check yours chaps when you get the opportunity.
As for the performance of the DV+, since switching to Revo 2+, I can't say I notice any improvement with the Revo Intake. Perhaps a very slight sharpening of the throttle response.
When I had a custom map with the factory air box, that's when I really noticed the DV+. It was way more responsive than the OEM diverter valves. I don't understand why, but it just worked the best. The DV+ does seem to cause some part throttle surging/shunting at urban speeds with very light throttle. I think that's because the OEM valve is very keen to dump ALL of the air when coming off the throttle, whereas the DV+ keeps some pressure in the manifold, which I guess some ECU tunes don't account for? Not sure.
