Very good breakdown of the product. Doesnt just advertize how good it is, but shows us the benefits of the before & after. I now recommend them to people.
Thank you Ryan! We appreciate your feedback and support!
Interesting to see the new update. I have the original kit. I'm interested in the new filter and turbo inlet
Thanks for stopping by the channel! If you're looking to update an earlier kit on the air intake side, please check out our Stage 2 Intake Kits which will combine the Air Intake and Turbo Horn (inlet) shown in this video into a package. Search for part numbers WCF100302 for LBZ and WCF100303 for LMM. 👍
I've been looking for a kit that can be color matched with my truck do you guys do custom color's
We carry ~35 different color powders in stock and can also special order colors from most major powder suppliers including Prismatic who offers thousands of options and provide recommendations for which of their colors most closely resemble OEM paint codes. If you’ve got additional questions or would like help placing an order for custom color parts, please give us a call at 630-277-8239 or email us at sales@wcfab.com.
On a stock LMM what rear wheel gains are expected ?
What kind of HP gains can be expected from this package?
While they are perfectly compatible with stock trucks, this kit really shines with (and is intended to help complement) other performance upgrades like bigger turbos and performance tuning. So, what you're going to get out of it is what you're willing to put into it. On a stock truck, pure bolt on HP gains are likely to be minimal. The benefits will come primarily in improvements to reliability, overall drivability, and efficiency mentioned in this video alongside things enthusiasts also tend to appreciate - like sounding and looking better than the stock parts. With these trucks getting older, your experience may vary, particularly if you're used to daily driving a truck with undiagnosed boost leaks. Addressing those can result in a much more noticeable performance difference before and after installation for what has slowly and less noticeably degraded over time. We haven't specifically run this kit in back to back dyno comparisons vs. stock because a low miles, showroom fresh version is now rarer than hen's teeth these days. Consider this however as a point of reference for how this kit will work alongside other performance upgrades for even greater gains: With a max effort performance tune and just an upgraded turbo inlet horn on a Duramax, it's fairly typical to see gains along the lines of an additional 10-25 HP vs. the stock part (depending on the gen of the engine in question). That same intake horn also provides the smallest measured air flow increase percentages of all the parts being upgraded in this kit.
@WCFab thank you for the in-depth response. You guys make a solid product.
I did and aftermarket intake manifold and now I’m getting a p0107 do I need a retune now?
This kit is designed to work with a completely stock ECM calibration and does not require custom tuning. Typically for a P0107 which is related to a low MAP sensor signal circuit, we'd suggest checking out the condition of / replacing the MAP sensor and inspecting / checking the wiring harness to it to make sure that the sensor is good and the wiring wasn't damaged or pinched during the installation of the new parts. If that doesn't get you anywhere, please give our team a call at 630-277-8239 to speak with our tech support for additional troubleshooting tips.
Will the lmm allow a Banks ram air just curious ?
Yes, the Banks Ram Air intake will accept the boot connection from our turbo horn for the LMM. If you were trying to put together that combination, look at our Stage 1 bundle (WCF100324), intake horn (WCF100412) and down pipe (WCF100703) as the best way to get the parts that you'll need for that installation. If you have any additional questions, please give our team at call at 630-277-8239 and we would be happy to help!
Does this kit need an lb7 up pipe?
@@kdolezal7 it does not.
can you buy just the airbox? i have the version without the box
We do not offer the air box separately. The design updates to our intakes to incorporate the box extended to a complete redesign of the intake pipe assembly as well, the previous design is unfortunately not forward compatible with the air box.
Dyno numbers vs stock?
DO you offer a non complient kit as i live in a non deq area???? 06 lbz here... please send p number... thank you.
All of our kits are emissions compliant performance upgrades.
