To beat him you need a set of stage 1 injectors, a TW or DP chip along with gauges it you don't already have them. Also with the bgger injectors you need to address your tranny or it will die a very short, hot painful death.
how was the tranny better? i thought they still used E4OD trannys ?

yep its a 4R100. very close cousin to E4OD but it has upgraded hard parts and seems to shift stronger in stock form.

it better but its not that much better that it would be worth it. a fully built e4od would be much better though a bit more money.

There's only a couple differences between the E4OD and the 4R100. The 4r has 2 extra sensors and the shift linkage is a bit different, other than that mechanically they are identical. How do i know? Because my trans builder swapped all my built parts from my E4OD into my 4r100, then took all the 4r100 parts and put them in the E4OD. Yes, in stock form the 4r has some updates but when built neither trans is any stronger than the other.

injectors, idm, hpop are all bolt in. IC is fab in, programming is an aftermarket chip. IDM and HPOP are nice upgrades for OBS trucks, Injectors are ok but stage 1's are better. Turbo is also bolt in but need SD up-pipes, pedestal, turbo, intake y

The 99-03 had split shot injectors which run on a different program then the single shot injectors in the earlier years.

Because they are Junk!! The programmers that can work like that are so generic they are able to. this also means less useable power and in most case higher EGT's.

I agrre with them bieng crap. I have a superchip max tuner 94-03. It was on the truck when i got it and i never put it on stock but there really isnt any difference between tow and off road mode.

Are you happy with your Diablo 3 position chip? And is that just for our trucks?
Thanks
John

For what I have now I guess I am happy with my chip but I always want more. This chip was in the truck when I bought it and I don't have any first hand expereince with any other chips but everyone, and I mean everyone who has posted about switching chip to either Dp-Tuner or Tony wildman have said those two are the tops. So soon after I do my injectors I will be getting a chip from one of those two. The chip I have is programmed specifically for my computer but not for the mods I have (injectors, hpop...). so it give nice power but there is more to be had.

Very good info but I think the point is being missed. The main difference between 99+ and the OBS trucks is that the 99+ trucks are ugly.
