Great news on the red line. I just picked a bottle of techron to run through the fuel system on my trip tomorrow. Will let you know. I have used techron in all my vehicles and really feel it does a good job. I can really tell the difference in my Land Rover Discovery after I have let it sit for a couple months only starting it once a week. Dump in a bottle fill up and head for the mud. Fun. I will try the red line next time. Oh as note..I had the chance to stand with my indy and compare 330 bits and pieces. The runners on the intake are different....the throttle body is the same diameter but different entirely. MAF...looks identical, same diameter except for the connection. The box has a different top..suppose because of the carbon filter. Mines gone. The fuel rail and injectors are very different...all stainless steel.
