on my 2000. i could only run about 17 degrees timin on nitrous and no knock retard.. i did a efi live custom os and went with a 2001 operation system and i can run 30-28 degrees on the nitrous

 

Holy Crap!!! That's a huge difference! I might have to look into this.

 

i put this all on with a stock cam and i went from 233 hp to 250.. seriously if you can find some one that can do custom operating systems i would definantly go with that..the afr is all done by manifold air pressure instead of going in to power enrichment..you can set your afr leaning at lower rpms and map for better gas mileage on the highway..

 

Yep 2-bar custom o/s is what I am running as well. You have to have a commercial version of EFILive to do an o/s reflash, but after the o/s reflash is done you can use a personal version to reflash the calibration data. Todd, did you buy HPT already?

 

Yeah, I have HPT, but I've just been doing the basics with it. I haven't done any WOT tuning yet, because I don't have a WB, so it's kind of useless. I'm probably going to go striaight to the 3 bar setup, but I can't find any info on how to hook it up to our intakes. I also want to relocate my IAT sensor first.

 

3 bar MAP should go directly in place of the original MAP right?

 

so if i got a tuned 02 pcm from lets say w4m as an example because i cant afford nelson yet and i have a 99 pcm right now then i should see a good amount of hp/tq difference?

 

where can i ge a 02 PCM??

 

I would try car-parts.com I've seen them for as little as $50. Buf from what I understand and what I read, when I do my custom 3 bar setup the PCM won't be operating like a 2000 at all. The way it's described, it'll be a whole new animal.

 

If tuned for it.

just like vanilla said, but if you have some cash to spend, get it from Allen Nelson along with a tune and lifetime upgrades!
