OK, from my previous post it was said the 99s have different cams/tuning than the later trucks and the 02s are best in the tuning of the 99-02. WOuld it be best to steer clear of the 99s? If I got a 99 what would be the best price/performance cam I can get for these trucks? How much is the nelson tuning? I plan to start out with bolt-ons possibly and eventually get the STS turbo setup. Just wondering if I should go older (99) and get the truck ccheaper so i can start the moidding earlier hehehe.

thanks, Brian.

I have a 99 and do have some problems with false knock, the PCM is the problem with the knock. If this next tune doesnt take care of some of the pinging Allen is switching to a 02 PCM, because we cant narrow it down to anyrthing else. Allen told me the later the year the less the problem with the false knockin, but 02 pretty much has the problem nailed. That would probably be your best year to buy but 99 is still a good choice!

My '01 is fine without False KR. When I owned a 1999 it was very, very slow.

What about 00s?

00 are great, nuff said!

Well it can be in early '00s also. Just log it and be sure.

'00s+ have the larger cam. That's one reason they're quicker.

Also, there's LOTS of problems with early '99s too. TSB, recalls, etc. Not the best vehicle around. If you're looking to buy, IMO... get a '00+

I have a 99 and I have to say that it is very slow, but there is a lot of pinging when you use lower octane fuel. I only use 93 and I really don't have any pinging anymore. Your best bet would be to get an 00'+.

Will switching to the 02 PCM help knock out the false knock and speed the truck up a bit, I know Allen said if this retune didnt work for me thats what he is going to go for. I am only getting ping on the top end, but I can tell in some circumstances where timing is being pulled when it shouldnt.

It's a constant 8° KR, it's crappy.

Timing should be pulled anytime there is load on the motor... in the midrange espically I'd pay attention.

Ya could also desensitize the knock sensors too.

I wonder why Allen hasnt already switched me over, I knew it could be a bit faster, although the tune is a badass upgrade over stock, i know there is some balls left in that truck, especially on takeoff.
