Dyno tuning

dyno tuning a street car isn't going to help you much......get your own tuner and do it yourself, for a $300 PT you can do a much better job then they will

Hopefully Matt can elaborate, but I think what he's so delicately trying to say is that a professional tune will far outperform a tune made by someone who has never tuned before, and/or has limited experience or tools (ie dyno, wideband). Especially if comparing the amount of time spent and risk involved.

Just because it's on a dyno doesn't mean it's only a WOT tune.

Have a pro do it. Noone here has EVER complained about getting a professional dyno tune.

Or just put nawz on it and smoke everyone on da str33t.

Yeah I have to agree with Matt, I've read far to many posts with people doing more damage to their cars by trying to tune it themselves. Just spend the extra money and get it tuned by a professional.

Also who said dyno tuning was 3 pulls for $300??? Dyno tuning is set by the hour, and any good tuner will tune your car until he can go no further...may be 1 hour may be 4 hours?

Dyno testing is usually 3 pulls for X dollars.... this should NEVER be confused with dyno tuning, making 3 pulls gets you a good idea of what your car actually makes on that given day with the given weather conditions. It's more about bragging rights than improving performance.

please show me a dyno that will put an engine through every combination of load: spark/fuel cells, map, pe, afr, temp, etc for $300 and i'll hand you $300 right now and take my 20 hours of tuning back......i would be willing to bet on a 3800 they will only touch your maf, gfs , and pe tables..........any good tune should start with a volumetric efficiency tune (which will take a few hours on it's own) and i would be willing to bet they wouldn't even bother with that......i wouldn't trust any dyno tuners in CNY to do a good job on slightly modded 3800.....

you will not get a better tune in this world unless you are tuning down roads you drive everyday, and i would never attempt ONLY tuning a car in 85 degree weather....

the tuners they are using are probably hp tuners, and for the price they would charge you, you can just buy your own

i have tuned several 3800's in my life......charge my friends $30 for a basic tune (what you would get from zzp or dhp 1.0) and $150 for a ve tune and the whole works ( about 5-6 hours of time)....i guarantee my tunes are more thorough and will perform better (ESPECIALLY gas mileage) then any dyno tuning around CNY

My car has been retuned for three different setups and has about 28 dyno runs on it. So yah, 3 pulls.

I say put your money where your mouth is. djnawzbag vs. nep.

John, you think Mike would be in? Twisted Evil

FYI, all your rule-of-thumb tuning times are for people who don't know what they're doing and use crappy pre-made excel spreadsheets to alter data.

Let me tune a car for fuel efficiency. I'll just unplug two injectors. It will get like 35 mpg. HAWT.

That is a GREAT idea!! I say you let this kid tune the GTX on the street, and then take it to New Era and see if mike can make any more HP or Ft/Lbs. It will also give this kid an idea of what kind of numbers he is actually making with his tunes.

Butt dyno tuning VS. New Era Performance dyno tuning

I'll tune any car with any mods on it for half of what they will........If someone wants to we can do a before and after...I've got one more year of a major in mechanical engineering and a minor in math, trust me, I know what I'm doing...YOU WILL NOT get a better tune on a dyno, boggles my mind why you guys think that...Is anyone here certified in any ASE fields??????

I've tune 2 of the basic 3.4,cai, dp, pems, to low to mid 14's........Tuned a silverado SS w/ cai, exhaust, to 14.7's from a 15 something......Tuned my own car from a 15.7 to a 14.9 w/o spray and 14.6 w/ 65 dry shot....And also tuned several stock 3800 and 3400's with obvious gains and smiles on faces

Tuning is not hard, the only goal your trying to do is maximize the amount of fuel for the most amount of spark throughout the powerband. And if you think a dyno replicates the streets you drive everyday, it doesn't even come close.

If your car isn't strictly for the track, which I doubt anyone's is on HERE, then your just wasting your money by paying them

So tell me, if I don't know what I'm doing....Don't you think I would have popped something on any of these cars by now?

And my argument is about dyno tuning a daily driver 3800.....I never mentioned anything about anything under 12 seconds. I would definitely take that to a dyno

I have an ASE in electrical, but what does that have to do with anything? i agree with everyone else here, that a dyno tune is better than a street tune because you can duplicate practically everything that u'd find on the street. and why can't you have a daily driver under 12 seconds? mayb ed will chime in with what he ran w/ just a 3.4 and pems.

Hmm... I never had any courses about GM Tuning in my engineering classes... Must have been an elective.
