Got it dyno'd at Dynolab, Inc. in Marietta, GA. Talking to Christian at Cobb tuning about the dip and going to do another 4th gear pull (on street) with logging for him to review. I am asking them to adjust the tune for free to match the specified targets shown on their website.
Since i have exactly what the map calls for and higher octane than required, i dont think 5.9 knock is appropriate and safe at all under load when the Denso ITV22's are installed. Also, if the car is overboosting beyond their 17.5psi max spike goal with tapering to 14-15 by redline, i am asking them to adjust the torque targets to meet that boost goal and not spike past it. I have the stock exhaust, BPV and intercooler so i think its fair to expect them to back their maps.
He mentioned that i needed to ensure my fuel pressure was up to spec at WOT, which i will be logging as well. I dont think a 17.5psi spike is enough to down the fuel pressure but we will see, maybe it spiked too high for the pump. Dont wanna drop $635 on a new one right now anyways!
285.3 and 308.8 with 15% loss accounted for is about 335 horsepower and 363 torque at the motor, give or take, so im positive i need the one step colder plugs (50+ hp over stock). Hopefully they will add a margin of safety and backed with Cobb's assistance we can level the boost out and A/F too so it will run around 275 at the wheels (if boost decrease is required).
What do you all think?
PS- thanks for the compliments, exhaust is staying stock b/c i want some longevity out of the motor and dont want that much more power, daily driver to work after all.
