I changed it to 91 with correction, and sure as $h** the car was smoother, gas mileage increased, decel was faster and smoother, slight kick in the pants difference, and traction light actually flickered in 3rd at 70... -facepalm
Update to this previous update:
Same driving habbit, and I'm returning about 15.5mpg, about 2.5 better than with the 87 RON selected. That's a bit more on par with the SL500 stock. The more I drive the more I realize the difference in power as well. It's so smooth now.
Next up is to get my new 16" electric fan rigged (thanks Steve), intake tubes, K&N filters, stock exhaust rigged up, then the state smog referee.
My registration is due August, and my plan is to visit the ref March. I wasn't nervous going into the build because both the 320 and 500 are considered ULEV (ultra low emissions vehicles) and have the exact same smog equipment between the two.
Well I could have done a bit more research than believe what I was told... The referee goes by the emissions date stamped under the hood (2004) and the engine swapped in has to be from a car of that same year or newer (supposedly). Well the shop that Bob was in contact with (where I got my motor) said that the engine came from a 2005, come to find out, it's from a 2003...
The fine print actually states:
"Make sure the engine and emission control configuration on exhaust – controlled vehicles are certified to the year of the vehicle or newer, and to the same or a more stringent new vehicle certification standard."
So I have some sweet talking to do. Emissions wise there is no difference what so ever between 2003 and 2006 SL500's nor is there a difference between 2004 and 2008 Crossfire's, nor the two together. I have to prove that a 2003 SL500 could be certified for 2004 emissions... Or he has to take my word for it.
Any suggestions?
