Just get rid of your superchips and get a nelson mail order tune FTW
Dyno tune is just for max HP. You still need a street tune to make sure it will drive ok. I've never done a dyno tune only street.

when i had my Nelson tune we went out and did my tune and it was damn near instant how noticeable the truck felt....
same thing when i had to switch tuners up here in DFW, went out and found some seldom used roads and tested it out in a driving enviroment
When I decide to get a tune... If it is Nelson I choose; which I am leaning toward, I will do it while I am on Air Force Reserve weekend there in San Antonio since I travel there once a month anyhow from Houston... There is no since in waiting on mail order... right? Then I can play with it too...lolQuote:

Make sure to make an appointment. Allen is a busy man
True true... an appointment is always the way to go.
Any suggestions when it comes to tuning? Here is what I have heard so far to begin with or what I would want: I want to run a 180 degree t-stat so it will run a bit cooler and reduce the chances of pre-detonation. Reduce the Torque Management by 75 to 85% and on the towing side 50% reduction since I do not tow anything but a trailer with 2 streetbikes it weighing approximately 1,500# and maybe an antique car trailer weighing a lot more. Delete the rear O2 sensors for future longtube headers. Increase the top end speed limiter too: 150 plus ... and increase the RPM range. And adjust the transmission for the vette servos and possibly a future shift kit. And possibly a cam... Any suggestions? Someone mentioned an "Old Man Cam". I also read about the 98 to 2000 year model cam or possibly a Z06 cam. Which would be the better all purpose cam; plus some playing on the streets at night and weekends?
Then which will give you the better MPG, horsepower and rear wheel torque using the 87 or 93 octane tune?
Street tune makes the most sense...unless you are just looking for a dyno queen. Dynos can be calibrated to show a lot of things that aren't real.
IMO, street tune & strip times are the only reliable gauge.
Street tune w/wideband tuning is the best IMO
street w/b tune,im running a nelson mail tune and yea ditch the programmer
Street tune .
Street or track is where you race not on a stationary Dyno .
Street tune for drivability
If you want max power from set-up you have to dyno tune.
You can set air/fuels with wide band, but you dont know what
differences you are getting at WOT with timing changes unless on a dyno.....
Take actual dyno number with grain of salt, but it will tell you if your
timing changes add any power or actually might have hurt.
Other wise you're just guessing on best timing at WOT
you need BOTH.
i do all street tunes but, recently ive gained access to a dyno. now with my street tune vs dyno ive gained 16rwhp by tweaking the car on the dyno. Street tune is best for overall but the dyno tells you if what your doing works best or doesnt.
i found out that by removing 2* timing i gained 1rwhp. this isnt much to brag about but hey its one more HP.
handhelds are a joke, and mailorders get you in the bleachers of the ball park.
Personally I wouldn't do a mail order. Do a live street tune since its you're DD
HP can go up and down due to temps changes in the air and oil/water, so to say pulling 2 degs and gaining 1hp is misleading.Quote:

That's why most shops charge a price for several dyno pulls, not just one, to be sure they get the highest and most complete dyno pull.
I have a question without turning this members post into a debate.
Why do you say mail order tunes just get your truck in the ballpark?
I would say with a good mail order tuner, you're truck's tune is 98%.
Saying it's in the ballpark is like saying the tune is just good enough for the truck to be mobile. When in fact, almost all of the mail order tunes we send out are more than capable of going out and racing and never needing a retune. Meaning, the tune is so close, it's not worth changing the calibration. Hundreds, thousands of tunes and retunes are on the street running great!
Even 4 years ago, my mail order tune was put against a dyno proven tune and my mail tune was .01 slower in the 1/4 mile. This was a lightly modded Magacharged SS truck. .01 difference could have been traction issues, not enough cool down or the pcm just adjusting.
Granted, we do have our issues here and there and we try to care of them, but if the tune is way off, there's usually a reason.
Take Ducky's and Jon's trucks, they are both sd tuned, I sent a mail/email tune for a big jump in injector change, both trucks were very close.
Ever try tuning the 60lb siemens injectors via mail, and on top of that sd tuned, it's very hard, but the tune was pretty close.
It's misleading to say mail order tunes are far from close, when in fact a lot of fast trucks are on the street. Sure I'm a little sensitive when comments are posted like that, but that's how I make my living, providing great mail order tunes that work and are very close to a dyno tune.
Let me know.
btw, thanks for considering us as your tuner! With the mods your truck has, a nice performance street tune would be just right for your truck.
We'll hook up the wideband and optimize timing, a/f ratio and make the transmission shift like it's supposed to for truck enthusiasts.
later,
allen
my reason for mailorder is ballpark. no way in hell can you dial every combo without actually tuning the truck. your typical mods yes sir, radical combos no way in hell. just to many variablesQuote:
