Hi all,
According to THIS thread, I've replaced my non-ST200 airbox, with CSVT one, as ST200 airbox is obsolete, and hard to get.
CSVT airbox make my ride sound very nice, so it will stay.
But there's no difference in acceleration... so, intake replacing didn't change anything
So, I dynoed her...
Where are my horses??
Please check THIS file - it is healthy (red) and mine (blue) ride torque and power curves...
The first one was dynoed at 57,2 F, mine at 86 F, so that's why I have less power up to 3500 rpm, I think.
But then, secondaries comes into the action, and "healthy" power, increases more, than mine... in the end ca. 20 HP is lost...
The torque curve is even worse...
After secondaries are opened, the other ST200 torque comes up, mine just do not comes down...
And secondaries are working for sure:

IMRC looks OK:
The piece of copper, which tells PCM that secondaries are opened, seems to be working...
Filters, spark plugs, cables and oil had been changed 1000 miles ago...
Ride runs smooth, starts flawless...
No problems at all, everything is OK with her, but she's too weak
So...what's wrong??
Too few gas after 3500 rpm??
Fuel pump??
I have ELM327 + ScanXL software + Ford Enhanced Add-on...
No CEL codes...
Which PID's should I check?
Air flow?
Throttle position??
