Ok guys!, I have a very early build 600 engine, I think the build date is something like 1/?/04????? Anyway it has gotten poor mileage since It was new, about a month ago I installed the rokktech sensor in hopes that it would hellp my mileage, it did not, all I noticed was a changed in smoke, the truck would black-out an intersection pefroe the sensor, now I can only get a light haze.


My question is with the rokktech installed, can I still get the reflash done for mileage, and keep the sensor or will timing be too advanced????????

Thanks!

Yes, you can get the reflash done and keep the Rokktech. The TSB you want to look at is 18-037-04.

That reflash seems to have helped a ton of people with 04.5's. My 04.5 when new was getting 7-8 city, 11-12 highway. After flash (had it done after 5k miles) I was getting 12-13 city and 16-17 highway. When I traded it with 46k, it would get 14 city and 18 highway.
