Knock and Misfires
Okay, I have no idea who you are but.... "He's making a tune, you're trying it...if you have a problem, he makes something else and you try it. You see the pattern?" IS THE TUNING PROCESS WITH ANYONE/ANYTHING. You can't expect any tune to be dead on right when you load it into a car. Have you ever tuned a car, or is all your time spent on these forums making asinine responses?
Proper tuning REQUIRES testing and adjustments, that is how you get the most out of any tune.

while you're at it, go ask a Republican if he thinks the Democratic party is better
that would be a great way to kill business... but its common ******* sense, you can try your damnest to "create" real world conditions in a damn shop..........its never going to be the real f*cking world
i'm sorry that you guys have fallen like sheep into thinking a dyno tune is where its at, but its not...
a good tuner and the right software out on the street, will have your car tuned better for you ENVIRONMENT IN WHICH ITS ACTUALLY GOING TO BE DRIVEN than any shop can do on rollers...
doesn't take a rocket scientist to figure that one out
no that isn't ricer math, that is common f*cking sense, if car A is 5mph faster than Car B in 600' and ran a second faster in E.t. than car B in 660'... Car B got taken to the wood shed
I can tell a lot of you are NOT familiar with drag racing, a difference of a second in E.T., a difference of 5mph in the trap, that doesn't look like much on paper... you should see it with your own eyes, its a mugging
and honestly, through the 1/4 it wouldn't be THAT bad, I mean its still several car lengths... but when you shorten the race in half and STILL lose by 5mph and a second... that is brutal
I can see why a lot of the people on this forum HAVEN'T posted up their track results... because at the end of the day, no one cares if you are putting down 330whp if you're running mid/low 13s

Trifecta nuthuggers just popped the hpt nuthuggers in the mouth with these last posts 
People bashed Trifecta way back when because dullards were googling cobalt tuning and found Trifecta and asked for the most boost and aggressive tune they could get and reporting back here with omg tf >all when they couldn't even tell you the difference between a pcm and lsd. Now we have come quite a way with tuning and more knowledgeable people have come forward and worked with vince to get his tuning to another level. Sorry hpt boys but the arguments should end, stick with hpt and use tf's options when you want to make big power.
I'm hptuned by m-dub and myself by the way.
Flame on!

NJHK has nothing to prove to anyone, he's been around forever and knows his stuff.
I didn't say a dyno shop, I said a engine shop you fool.
Anyone who makes big power dyno tunes, it makes more power and it's safer (for your motor and the public).
You guys sound like idiots right now trying to argue this.

This whole site is full of nutswingers such as yourself. I have a Trifecta tune, but if I lived near one of these guys that could HP tune my car correctly, it would have been a harder decision for me on which tune to go with. The fact is no one within 500 miles could tune my car as good as Vince did. I'm sorry if you really believe that a dyno is vastly better to tune on then the street, that's not my problem. I really don't know which is better, but from everything I have read, there is more then enough people on both sides of this arguement that I can safely say that NO ONE has the right answer.
Lastly, if NJHK believes so strongly that he is correct, he should be able to provide some kind of evidence that a dyno tune is better. But the fact is that what he says is an opinion, and opinions really are like ********, we all have one and they all stink.

I think that was towards me? I never said "dyno shop" either, just saying.
What was this thread even about to begin with?
i'm saying an "engine shop"... think about what you are saying: a car is healthier being tuned in a controlled environment... all the parameters they use to tune the car, can be found with Trifecta/Hptuners... in fact MOST engine shops probably use HPtuners....
the difference is THE ENVIRONMENT... i'm sorry, you won't create it sitting on rollers

I'm not **** talking Trifecta, or saying HPT is better, hell my car is street tuned by myself on HPT, I'm just saying that you guys are silly for thinking that street tuning will be better than dyno tuning.
To the OP, it's probably your tune, sorry chum.

When I drive I see various amounts acceleration/deceleration, air resistance, rolling resistance, etc. Like I said, no one in this discussion can say with 100% certainty they are right. Both sides have valid points.

But thanks for caring about my *****.
Street tuning and dyno tuning both have their advantages and disadvantages . . Now if you can find a dyno with it's own wind tunnel .....like the big car manufactures have .... that would be the best of both worlds. It hard to say one is so superior to the other.
"TECHNICALLY"... Your sposed to tune on the dyno, and get everything looking good, THEN! take it out on the road and tweak the tune for that. thats just the way i was taught to tune a car in school. Wish they would have gone into more detail about actually tuning the car though...
Thank god!! that guy was a doucher.

The dyno is the best and safest place to do a baseline. Also if you have a sniffer it gives you a good idea of an AFR if you don't have a wideband.
Wow, thread took of a bit in the last day lol
Anyway, datalogged the car for vince and he said that the knock and misfires are minimal and there is no way to adjust the tune to change them. He said that that amount of knock and misfires are common. I'm not sure how many of you guys experience any knock or misfires like this. Knock usually only occurs when letting the clutch out in first and second and misfires are random, they appear at idle and at almost any random point in normal driving. Is there any way this is attributed to noise? He said its likely caused by 'piston slap' or some other type of engine noise. My A/F is 14.5-15 with a lambda of .9 to 1.0, usually sits around 1.0.
I will probably just play it safe and change plugs when I get a chance.
Cant see that being the problem but who knows. I'll do a search to see what they need to be gapped at but if anybody wants to post here that would be great.
