Performance shift will make no difference in what RPM you run at a fixed speed. 1500 sounds fine for OD at 55.
At this poing, I'd just ditch the platinums, and you should be in pretty good shape, although a better breathing airbox or intake would improve mileage.

Ok OK. Foghorn really taught me a lesson there.
What'* your best guess for a spark plug set for me if I'm running stock pulley. NGK TR55 at factory gap?
You think that my warmer exterior temperature should make a difference? Example today, wednesday, september 1st. at 8:48 am the external temp is currently 94F with 70% humidity. Expected to rise to 110F.

I've seen the mods on your car and I'm drooling. Obviously it'll take me a while toget there. But I really would like to start with a cold air intake. An intercooler later along with a pulley and a hotter ignition. What brand is your cold air intake? Where did you buy from? Cost? Any additional mods required in the engine compartment to let it breath? It seems to me that being behind the left headlight assembly doesn't let it get enough fresh air.

Intercoolers aren't available for our Series 1 L67'* but an option is in the works.....stay tuned. My intake is one of 6 produced by ADTR, with a K&N RX-4750 filter, and a custom heat shield (I made it). I have a ram air feed from underneath to provide plenty of fresh air. It runs 5° hotter than outside air temps above about 20mph.
Ram air also cools the SC from the other side You can see the duct in my sig pic.
Do the 180° thermostat, drill two 1/16" bypass holes in the flat. Add a trans cooler. Your climate really requires both these mods (I lived down there, too). THEN do the intake, pulley, and exhaust.

Great, thanks for the info. Question (don't you get tired of all our questions? )
Do you have a tech article on how you did the ram intake mods on your car? Also, I see that your blowing air on a specific part of the SC. Why there in particular?

The inlet to the SC behind the TB is the hottest part of the SC. Even hotter than the lower surface mounted to the lower intake manifold.
I'm cooling my hot end of the SC and TB that way.
Hope you're up to some reading on the ram-air:

Nice work! You used the exhaust tips, huh? What do you think about placing scoops inside the bumper? Just above the first fold.
Also, I bought a Hayden 3647 adjustable thermostatic fan control kit to install in my car. The darn thing is set for a regular two wire fan. but I can see that our fans have four wires. I assume that'* for the HI-LO speed settings. How do I know which wires to tap? Any ideas? Diagrams?
Also, although I replaced plugs, wires O@ sensor and I gained responsiveness and power, it still seems to guzzle gas. Example. I filled it up (18 gallons premium 91 octane) and I have ran 94 miles and it'* showing 5 / 8 of a tank left. Again,rpm'* at 55 mph are 1,500, at 65 mph 2,100 no hesitations. Any ideas? EGR, PCV? Fuel regulator seems fine as well as pump. Driving conditions are heavy traffic with at least 40 minutes dayly of making line at high temp with the AC on. Have not driven it with a heavy foot on porpouse so I could check this fuel thing.I went to the extreme of having my wife drive it and I followed on a motorcycle to smell the exhaust. Nope. no rich smell. I'm baffled!

EGR will throw codes and set a light. AC is robbing mileage. How old is your Cat? Does it rattle when you kick it?
It may take time for your O2 to settle in......but really the best thing you can do is a FULL tuneup. In traffic and AC on is the worst thing you can do for efficiency. You need to take a long roadtrip to determine what the car is capable of.
