RE-BURN Question for Webmaster

Ken, I will eventually (not too soon) get 4.10 gears, shorty headers, and some high flow cats. Can you tune for all of these without the truck running lean?

Yes, we can handle that and get the A/F right. Its not a major modification and doesn't require dyno pulls for the A/F.

Thanx man!

Openclasspro: Explain a bit more about what you just said. I'm not too mechanically inclined.

in the 2nd 02 sensor- i installed a psi gauge and measured the back pressure of each side of cats- while driving in 2nd gear at 5300 rpms - back pressure was around 1 1/2 psi- which is next to nothing-phil

Ahhh, I see. Well, I'm the kinda guy (at least for now) who lives by the saying, "Every little bit helps." If I wasn't planning on totally tricking out my truck, I would probably steer clear of modding it. Besides, that's pretty cheap hp.
