Bringing back the FSP discussion
This is install on a 04 SL55 with 2nd HE and bosch 010 pump wire to be always on. OEM exhaust OEM intake.
installed 77mm FSP with RIQ tune. it is the same black FSP, prob a UPD brand one. It is day and night. So much more response and power. Tony say I should have 490hp w 550tq at the wheel.
What I notice is .
1. immediate power. response is huge difference compare to stock pulley and tune. It is truly a beast. Scary to drive at first. got a little use to it but still scary fast.
2. trans is shifting harder with the added power.
3. No more that little squeak sound when I'm driving slow in parking lots when Im pressing the accelerator to manipulate slow roll
4 No noticeable rattle sound that people talk about with FSP in engine idle. - i did change the SC oil at the FSP install. if that's anything worth mentioning.
5. No noticeable difference in MPG. It is still pretty crappy at about 15mpg
6. SC whine!!! is intoxicating.
