Stillen HFC vs. BERK HFC

Kyle@STILLEN · 04-14-2009, 12:20 PM

Hey Guys,

Sorry that we haven't jumped in here yet. Josh and I hadn't seen this thread until it was brought to my attention.

It's pretty much a gaurantee that the hi-flow cats will set off check engine lights. We are currently working on a way to defeat that though and hope to have that solution soon. Our engineers are testing two different ways to fix the CEL issue. We would like to stay away from tricking the ECU if possible.

In regards to the advertised horsepower output. You are correct, we have a typo on the website and we will correct that ASAP. The dyno for the G37 is the one we should be using for the 370Z but our literature is from the 350Z.
