I know I haven't dyno'd yet but today I finally got to get some over
7k runs seems to more I peg it over 7k t better it responds I have a tune on my car now but want done with that one either , I decided to wait till after I get my HFCs installed to finish the last 2 revisions . But for sure mid range is improved over the stock manifold .

Sporadic Cell for first 3 days maybe (less than 100 mi).
No cell since (over 900 mi now).

Misfire or cam timing codes, ?

Dyno tomorrow am !

Not sure ecu just adjusting maybe.

If your light is staying on then could be something not installed right.

I fixed it found a vacuum leak at the mani, Did some pulls over the weekend to get my tuner the "new" logs, Didn't feel like flying down the HW at 125 :/

The dyno experience was a NIGHTMARE, the thread is here, Place almost blew up my Tcase (AWD light was blinking) !!!

Sorry that turned out like it did. Trying to tune a car with vacuum leak...not good..lol Sounds like you have resolved that issue, interested in here the numbers with that intake.....and yes..someone telling me they never tuned a Z would not be cool...

Not concerned with redline hp/torque.

But at midrange you definitely see increases with this product right?

Yes you do,

Look at my TQ spike under 4k. Again I have my VVEL tuned but still that spike is NUTS, :)
