Losing time on e.t. with dynotuning?
Losing time on e.t. with dynotuning? I have heard a some things about dynotuning. I am iffy on dynotuning my car because of losing time. I have heard that some times when you take a car to get dynotuned you can actually lose time. Sense some tuners don't take certain factors in the equation.

I know up here cars like to be at 12.6-12.8 A/F to run there best time at the track. On the dyno the most power usually comes at 13.0-13.2. The the track is only 90ft above sea level. I would just get you car dyno tuned the car will respond better idle better and be much faster than it is now. You'll gain more with Texas speed dyno tuning it than your Diablo tuner thus you track time will go down.

Contrary to popular belief, there is much more to dyno tuning then many people believe. Like many trades there is a wide range of knowledge, experiance and skill level from dyno shop to dyno shop. That profession does not require tests, licensing, etc, anyone can buy dyno a become a dyno tuner. Just because someone made their car fast and now tunes others does not mean that he is a good tuner for you. Not to mention, seat of the pants, grudge racing and even a timed quarter mile run is not usually a very scientific way to evaluate a good tune, too many variables. But, as most engine performance enthusiasts usually find out, you can accomplish more on a dyno in one hour then many expensive weekends at the track, with a good dyno and dyno operator, at least that's how the pros do it.
So if i am running ok right know should i Dyno tune or maybe explore other options like:
downloading tune to diablo programmer(risking being inaccurate)
Buying Hptuners or Ls1edit
using Maf translator with air fule gage to test and tune the car at the track. what do u guys think?

personally i went 3 tenths slower the stock with a dyno tune by a well known sponsor even though on a dyno I made an extra 70+hp/40+ftlb. A dyno should usually be considered a tool and not the end all be all to tuning. Keep in mind there are many liabilities shops are not willing to endure doing a "street" tune even though one probably should be performed on each car to some extent.

I'm a firm believer of street tuning.Most of my NA race cars never hit the dyno unless they aren't registered.
The sad part is most people want to gloat over high dyno #'s instead of a fast track/street car
A big problem with that is most tuners don't do PT tuning anymore. They strap it on a dyno, put the A/F at 13.0, and charge you $400 for an hour's time. I fully agree with you, PT/street tuning should be done before the car is ever on the rollers for a tune.
