Loosing Power

[JS.CS.]

Hi im running m4cs with tuned.
when i did first tune, on dyno it was 507 hp, 71.87 torque.
at that time, i got intake, full exhaust that's all.

now i changed it to better intake, got WMI kit, TCU.
In my knowledge, it has to be more power but boom i got just 472.06hp 69.93 tq with meth, 442.38hp, 61.49tq with out meth.

its make me crazy. on the road test (such as drag test) now is much faster.
IAT is fine because of WMI, Ignition is looks fine i think.

I was talked with my mapper and he said i have something problem with my car so i been to the technician to check it out, everything was fine. LOL.

I did the dyno on the same shop, similar temp.
I have no idea whats going on.

How is it possible 472hp is much faster than 507hp on the same car.

If you guys have any idea to check, please let me know.
Turbo, WGDC, IAT, WMI, Exhaust, was ok when i checked.

Sorry for my English and thanks for reading.

Could it be traction? Extra power will only make the car faster if you can transfer it effectively to the pavement. Catalogs will help determine if there’s an issue with the engine too, but the Dyno results would suggest it may be ok.

yea you make sense. maybe the traction can be.
and i think i got some clue!
in WOT sport+, my WGDC is just 15% at 27psi.
i read it should be around 90% at 27 psi.
but i don't know what is the problem. do you have an idea?

Re-flash, reset adaptations, and give it a few days of regular use to re-learn. Hold off on the WMI until after it re-learns and the power comes back.
