Have made the necessary adjustments for the ECM for the oversize wheels?

Don't have any idea how to do that

Does anybody else have any suggestions

OK I take it you went into this blind to the problems this can cause. I your case I recommend that you purchase a computer reprogrammer for your truck, something like a Bullydog or a similar unit, that way you can make adjustments to the programming as you add or subtract equipment, or if you want you can reset back to factory settings without a big hassel of chip replacement inside the ECM.

What system would u recommend and how do I go about the factory reset that u. Speak of or what chip I mean for ecm

I like the Diablo Sport Trinity, but the Edge CTS is also a good unit. To reset the ECM to factory you disconnect the battery negative cable, turn on the headlight switch, wait around 30 seconds or so, turn off the headlight switch, reconnect the battery cable, then drive as you normally would for at least 15 minutes.

Have u heard any good of the bully dog triple gt

So far only one of the 4X4 guys around her has one, he really likes it, he says the only drawbacks are the screen size and the price.

Well thank you for the help I'll try some different things see what happens and I know I'm going back to stock tires

Well I tried it and still doesn't downshift going up hill like I said it has 6 in lift with 23 in wheels and just doesn't shift until I floor it going up hill
