Supercharger w/ TRD Exhaust
i might be losing it, but a few days ago i thought iread something along the lines that the s/c wasn't developed to work w/ the trd exhaust. something about the s/c should be stand alone.
anyone have any idea?
am i losing it?

elevation effects
In a semi-related side note, does anyone want to take a stab at fuel delivery mods when at altitude? I.e. if I'm at 6,000 feet now, I want to say I'm only gettin 75% of the power you guys at sealevel are getting. Does that mean i'm only using 75% of the fuel?
Where I'm going is order of modifications (i.e. when to put in the fuel pump and injectors, if ever).

I have the TRD s/c, headers and exhaust. It runs fine. Yes it runs alittle lean at top end and the adding of headers did help with ping. I did remove the aftermarket intake since that worked like crap with the s/c causing it to run even leaner. Once fuel mods are done, I'll switch back to the intake. But, no probs running a total TRD set-up

This is purely a guess, but I'm willing to bet the reason you're only getting 75% @ 6000ft as compared to sea level, is due to the lesser amount/lack of oxygen. Poor oxygen = poor combustion, which I would guess means your consuming the same amount of fuel as sea level, but just burning it inefficiently. Your ECU's probably senses it and tries to adjust, but unless you live @ 6000ft, it may not have enough time to adjust properly.
Just a guess though....

I was thinking 75% of the oxygen would mean that the O2 sensor would lean out the fuel till you're using 75% as before (i don't know if there is a linear relationship, but would guess so).
I do live at 6k feet. Where I'm going is when traveling into the hills I'll get up to 10k and 11k. I know that the drag racers, when they come to the mile high nat'ls overdrive their superchargers. I see a lot of talk about how its not worthwhile, but am wondering if that's only true for low-landers.
It'll probably take a few years of saving money, adding mods, and testing to determine (which is why i'm hoping some tech-head lives up in Breckenridge)

I live @ ~4000ft with my TRD Headers, CAT and charger often driving over 9000ft for my weekends. I have never regretted the extra cost of the TRD items. I still blow right by Jeeps with V8's even at elevation. I might be running lean but it has caused any issues and I'm up to 120klm's now and counting. The headers did stop my ping as they were installed one year after my charger (not available at the time), and I think they should go together as it ran much better after they were installed.

I think at our altitude you shouldn't incur a lean condition as much as our flat land brethren;I am applying my knowledge from my turbo Eclipse which I was able to run more boost on the stock fuel system as compared to my sea level counterparts. Having a little less power gives us a bigger margin of error.
