Default Dyno tune vs Mail order

Do you guys think a Dyno tune is worth the money over a good mail order tune with a car with the mods in my sig????

I know it would be if it was a H/C car...

Thanks.

P.S. Car also has a fuel system and all the small stuff.

get a mail order, have them tune it safe. There should be enough in the factory tune to cover it.

I'd just get a dyno tune...

By the time you get a mail order tune, and a few dyno pulls, then send your psm back for an update, then get another few dyno pulls...well, you've probably just spent the same amount of $ as a dyno tune. And your car wasnt out of comission for a couple weeks while your pcm was in the mail.

I have full bolt ons, and got started off with a mail order tune. AFR was off--in the 11's. I ended up getting a dyno tune (from Brian at PCMForLess) and it took him 3 pulls to nail it spot on. I suppose you might get lucky and the mail order tune will be spot on....

Dyno tune. I had a PCMforless tune in my car. I only got 6mpg because they set it safe..which is rich. I couldnt stand it.

my advice is Dyno tune. no crappy mail order. they are not physicly tuning your car, they are just putting in specs on what it should be......dyno tune they are in the car, seeing everything, and tune it to the maximum performance.


go Dyno tune. if you can make to Rockford, go to Simpson performance. his SN is BoostJunkie on here. he has tuned tons of LT1's.

I would just get a mail order tune with a few updates. I used Ion and sent it back to him once and my tune was dead on. I had some problems with a little cam surge and paid for a full dyno tune thinking I would get a little more up top as well as fixing my driveability problems, but no dice. Same amount of power and I still have cam surge....not as bad as before, but still enough to be annoying. If I had it to do over again I would have taken the down time to send it back to Ion again for another update instead of spending the moola on a dyno tune. BTW, my car is a LE1 H/C car that put down 395/375.

go with the dyno tune. as the first guy said, make sure your A/f ratio is good while spraying. and if you run on a dyno and use a data logger you can see exactly what your engine is doing through out the entire RPM range.

Where are the DIY-ers? Tunercat or Lt1-Edit oughta be in the candidate list, imho. I've not been there yet, but tunercat is going to be my choice. YMMV, as always.

A dyno is not the same load as the car going down the strip, how many of you stop to think about that.

A mailorder tune from a reputable tuner can be pretty damn near perfect for most cars. A few years back when one of the Impala guys was looking to push the NA record down some more he trailered his EW mailorder tuned car all the way from FL to OK, Ed found single digit power gains. An ignorant person would think that bad but an intelligent one would realize that just showed how great a job Ed did on the mailorder tune.

Dynos are absolutely useful tools but most of you think at little too much of them.

EXACTLY... As long as you have the desire & patience. I just like the idea of learning the basics and tweaking it on your own so, in the future when you add more mods you can DIY again. I'm starting down this road soon.
