Diablo Sport Tuner

[Postie]

Just picked up one for the Vette, anyone out there have anything to say about using it on a a C6 LS2, Does it help at all with Performance? Is it relativly easy to use.

Obviously I know a proper Tune by Manny is the way to go, but has anyone tried it or have anything to say about it, Good and Bad points please.

I had it on my car before I modded it. They ran the car on the dyno an got the baseline results. Then they uninstalled the "tune"... And ran it on the dyno again. Nothing... No difference. Same jagged curve and car made better power "under the curve" stock.

I have used before on various cars and the Caddy & Vette also.
If you are buying used and for a cheap price it has its benifits
but still not good as a real dyno tune.

For me on the Caddy just wanted to kill CAGS and extend the
fuel trims for hwy driving.
One the Vette I used for CAGS and adjusting the fans along with
the performance tune when the car just had ijust a intake & headers.
Once we did heads and cam the only good option was a dyno tune
done through Manny.

For a basic mod'd car its ok but if you have cam, heads etc go
with a prof dyno tune and you will see a huge difference.
Play around with it for a while, you can do some logging with the
unit but found it slow in response. I used a LS1M hand held when
adjusting my Long and Short trims to log my data and print in Excel.
