Should there be further recalibrations to not redline so quickly?

I had champion put in a custom carbon fiber box with twin horns, dry filters, no problems and no error fault.

Vivid has been great, but i cannot take a chance on voiding my warrantee because of varius faults. Further i have a tip and it totally thru off my acceleration and shifts between 2-3 and 3-4, although the sound was great, with what i have on now, I have sound, power (even if it is seat power, same as k n) and piece of mind.

Lots of engineering and R&D. A total package that works together

I get a kick out of hearing and reading the claims from the Aftermarket add ons, and I have to say is, "There's a Sucker Born Every Minute"....to each their own...

Ok dynoed the 911S today for those that want to know! Intake Temperature was 95 Degrees for all the runs.

Baseline Dyno (Engine is Hot at 175 Degrees): 308.7 RWHP
Baseline Dyno (Engine Cooled Down to 100 Degrees): 316.3 RWHP
K&N Dyno (Engine is Hot at 175 Degrees): 316RWHP

I have come to a conclusion on my dynos for the 996 and 997. The K&N filter gives tremendous gains in the midrange as much as 20-25RWHP! I was able to do several dyno runs with the K&N filter just installed. Initially it made less HP around 313-314RWHP the more it was dynoed it seemed that the ECU was learning the new changes in the intake system and gained HP everytime. I stopped dynoing when I got the 316RWHP results. I have a good feeling if I go back it will make additional HP if the engine was cooler. I made more HP at hotter temperatures compared to the baseline run with the engine cooled down! I will now say for a fact that for $299 there isn't a better deal out there for performance upgrades. So far I have no CEL on either car.

Look at the charts below you will see the that the Blue Line (K&N Dyno) has brought up the entire mid range line up! Peak HP remains the same according to the dyno sheet, however like I said before the K&N dyno was done with a hot engine and the ecu is still learning. The baseline dyno with a hot engine is 308RWHP and the K&N Dyno with a hot engine is 316HP. So in a sense it did gain 16RWHP! I didn't have the time to let the car cool down again and do another dyno with a cold engine and K&N.

Other than the added benefit of fast response and HP gains, the sound alone is worth the price!

Here is the car.
