Getting ready to modify my 06 V6, and was going to swap out the rear gears first. I want to find what gears I've got to begin with, but am having a hard time finding the RPO codes anywhere online. Have you come across any useful sites that provide detailed specs without trying to sell you a new car?

The car pulls SOO much harder esp thru the first 3 gears now! I was going to wait on a short throw shifter but I think that might be next on the list since when I'm really getting on it in first few gears, I can barely keep up with the stock shifter.  And the higher rpms don't really seem to affect it much driving highway wise. It's about 300 higher then was before but that means 70 in 5th is just shy of 2500ish....which is completely acceptable to me. And it also puts it in the sweet spot for a downshift to 4th or even 3rd.... 
Going to get another dyno done sometime this week or next and check the a/f and make sure set correct after the 93 race tune by Bamachips and also see if with the addition of underdrive pulleys and a good tune, if I can break 300 to the wheels. ( was 289 last time on a canned tune running 14 to 1 ratio )
So we see, I'll keep you updated :-) |
