I DO agree with you sir! But 1/4 mile (trap speed) is still a test of the driver, weight, how fat my fat *** really is etc... (How's the Viper? I haven't checked your thread in a while) |

You are correct in that there are variables that will effect trap speed... but with all things being equal, it will be a true read of horsepower. Just like dyno numbers have so many fighting variables as well. (The Viper is down again. I had it back for 2 weeks during breakin before it blew again. The motor was starved of oil, so the bastards didn't put enough oil in. The motor is still being diagnosed...2 months later)

SOB's... I hope they're fixing their f-up for free! If you find any parts that are in CA that you need someone to inspect or ship parts out to you, I am more than willing to help you out and the poor Viper... I love that thing |

If you think tuning a car is only for getting more power, I can't help you.

No, we can help. Tuning is not necessarily to get maximum gains. If AFR's are measured and are safe, then you probably don't "need" a tune. But like mentioned before, having the ability to adjust a host of other parameters is very nice. Elevation will be critical as well if it's vastly different and your car was running 13+ at sea level. It could spell doom when climbing up a mountain if the ECU can't compensate. These ECU's are an engineering masterpiece. They are smart as hell and will sometimes save your bacon if some asshat advances timing too far, or leans it out too much, it will gradually try and go back to what the motor likes.
My dyno untuned looks damn near identical to my tuned dyno. Not only that, I didn't gain a lick of power. Best tuned and untuned run was 310 whp (SAE). They were 9 months apart. But that tune fixed a lot of nagging issues I was chasing. I started at 280whp (with all my mods in August) on the first pull of tuning. That tells me the car was running like a$$ when at it's best was 36whp higher. Tuning helped me get back up to 304whp (DIN [300ish STD]). Four months later when GTM rolled it off the transport truck and ran a quick pass, it pulled 310whp STD. Moral of the story, even though my numbers ultimately came out exactly the same, the tune is what got everything back to where it was. Sometimes running a dyno immediately after a mod isn't the greatest determining factor of improvement if 2 weeks later, the ECU starts doing it's own thing and throws a wrench in your spokes.

How will you know if the car is running lean or rich? What are the signs and symptoms? So I will know if my AFR is just fine. Without the aid of diagnostics.
so far my exhaust tips are not black with carbon. But I smell unburned fuel everytime I start the car but someone said over here its because of the HFC. |

If u put extra mods on the car you would be foolish not to tune. Clean under the curve, all the other little things and to make sure afr is good n not lean. The computer will always compensate but ur prolly making it more difficult for ecu to compensate. In the end a tune is like 500. After spending all the money on buying an Infiniti and the expensive mods for this car, why skimp out on the tune that will help greatly reduce detonation? Makes no sense to me.
Good luck, to each his own. |

Depends on the car...
My first couple pulls pre tune (on mustang dyno) were 275-280whp. After 301whp with a higher redline and a nicer curve. For me, it was worth it. For you, going on inflated dynojet numbers, you think it isn't.

yeah its been said before but damn wtf wrong with people thinking that the purpose of a car and dyno's and tuning etc is just to hit a magical peak number so you can brag about the size of your **** you don't have.
Tuning makes your car run smoother, better, gives you more linear power, increases low end as well. All these are great benifits. And thats on a stock z. Tuning with mods brings the car back into the sweet spot, can help gain back some mpg's, again maximize the effectiveness of the mods etc. Its always a good idea to tune, just normally not as necessary unless you have many mods. |

Maybe the Dynojet you were on the numbers were inflated but not all dyno's are the same,as for tuning they are a very good tool you just have to make sure that your numbers aren't altered.
