Based on that information, I'd have to agree! Do you have a link to the source for this (or should I just search for fastmatt threads)?

Ahhh - as I suspected it appears the fuel maps are being modified by the SC tuner. This isn't the same as letting a MAF system adjust the tune on the fly.

so in real laymens terms that a paramedic can understand. Does it pay to mod things like air intake exhuast and chip, or is it not going to do **** to the car with our speed density systems. Also is it true that chargers are run by fly by wire at the throttle.

yeah and they also make the engine compartment look prettier!

Yes, it is worth is to mod your car with intake, exhaust, and especially a chip (which will encourage the speed density system to take advantage of your mods).

Yes, it is true that Chargers are run by fly by wire.

yes... at the srt track experience, the instructors at the drag simulation had the actual throttle assembly out of an lx car and it was definately "fly by wire"!!!!

Not true, as I said a couple posts back they got a very large increase without the SC. They used it to pick up the last 26 or something like that.

To me, not really! Unless you do headers. The other stuff like intake and exhaust will not give you anything you canf feel. Scratch that, a lot of people will "think" they feel it becuase they hear it. Not worth the money to get those returns. Slap on a cam and heads then the other smaller mods make a diffrence.

First it was 72 with heads, headers, cam. No computer changes (your words). Now it's 26 or something like that (your words again, and much more likely).

Whatever - either speed density versus MAF works like I've outlined and you're intent on arguing a weak position by changing the terms of reference, or DCX has designed the only speed density system that emulates a MAF, and the aftermarket pcm-tuners are snake-oil.

I'm happy to agree to disagree, and respect your right to have a differing opinion. Cheers.
