gen2 stock injector size and fuel pump

[anwagbo3000]

So at the end of the day the car dyno numbers where pretty much the same, no big differences so I don't need to update my numbers

[panic]

a range of 240cc to ~300cc/min

That usually means that, since the duty cycle of factory injectors doesn't run above about 80%, that the injector flow rate is perhaps 375cc.
If you need more than 338cc (90%), you need a bigger injector.
Why not just run big injectors? Poor low speed response, poor atomization, very complex - let's just say don't.

You're at 14:1 under what conditions?
If it's WOT you're about 1 minute away from a muted "BANG" noise, followed by a red light on your dash and smoke out the exhaust.
If it's at high vacuum steady-state cruising, you're subsiding the Saudi family.
14:1 is a suitable ratio for light throttle tip-in (like you would use to pull a hill without losing speed), but little else.

Didn't they tell you?

because they use the gross weight of 4400lbs which is on the inside of the door instead of the actual weight which is 3200lbs.

If that were true (my opinion: no), the car would show less power with lower weight dialed in.
Either they told you something different or more complex than you posted, or they don't know what they're doing.

^panic, actually you are right, the less weight did yeild less power, but not anything noticable, that and all my conditions were not the same as my first day that I dynoed, the first time they did everything right, they had the fan running not to mention it was colder out, when I dynoed saturday it was warmer and they cut the fan off after a while not to mention they couldn't get my car to sit right on the dyno, meaning it kept moving side to side, but once they did do a good pull or two, they got numbers back that were within the same range as the numbers on my first dyno day, I believe my whp was off by about 4, and torque was off by 3, nothing noticeabale like I said

And as for running lean at 14, I was told as long as I keep 93 gas in my tank that I should be good, these guys know what they are doing and I vouch for them man, they wouldn't tune me for something that would lead to my car having a early demise, my tuner(jason) is a engineer, not to mention he knows cars like the back of his hand, he works with josh and worked with him during the cpe production(I believe), so they know the gen2 pretty well, but thanks for your input.

[panic]

Again: you're at 14:1 under what conditions?

[anwagbo3000]

I'm running lean at 14, I have the tunable cpe mafci and a custom catback exhaust system with the trd muffler

[panic]

I give up.

Panic just wants to know if the 14:1 is under low engine stress-idle-cruise, of is it is 14 under wot.

[anwagbo3000]

oh ok, i understand what you mean now, sorry for the lack of understanding, give me a sec, i will contact my tuner, gotta get to my meeting.........

[anwagbo3000]

ok, after talking with my tuner, he corrected me, he told me that he would not have me running 14:1 because of danger behind it.

"your running 13.2 at wot, all other times the car will target 14.7 as that is stoichiometric on pump gas, all cars target that afr at times other than wot"

in this case, the middle man(me) got mixed up with info, my apologies
