Cotton gauze filters tend to outflow foam filters in general.

Here is a filter test to have a look at.

Generally cotton gauze flows better and paper filters better. Foam doesn't seem to do either as well but seems to outflow paper a little.

I recommend using TTM. Shop tools are required to do this.

This is the same "off the shelf" tune.

I'm wondering if the +10HP from the removal of the charcoals and K&N filter addition is actually more driven by the leaner AFR condition that I keep reading this creates.

I would be interested in seeing the AFR curves for those pulls to see how they differ, if at all.

Un-tuned the filter removal did not cause air/fuel ratio to change.
Less restriction = more air = better numbers

Which shop tools are used? To me looks like a razor blade would do the trick.

Great results Jeremy!

I'm considering swinging by your shop today to finally move forward with your tune (and seeing the charcoal/K&N results, also get those done at same time). Hopefully I can get the same 425whp you did since our cars stock had almost identical dyno results.

Any updates as to when we might expect some exhaust numbers?

A good heat gun, die-grinder and a razor blade is what I used. Not hard to do with the right tools. This mod could easily go wrong and cost a new airbox...

Any idea how dealers would likely view the k&n filter swap and airbox mod with regards to warranty issues?

AMGeez

What is the process for purchasing a tune and what is the best process to preserve warranty on a tuned car when bringing it to a dealer for service?

My OE update is the bomb! Lol I was driving the car again today ( not my daily driver ) and I can't stop smiling on how this thing pulls. Thanks again for the update. Next time your in town we will go out to eat instead of getting take out even tho those baby back ribs were on the money btw I got 433hp and 395 tq to the wheels. He did taylor the tune to my car FYI.

Jeremy is top shelf...
