Thank you Cryo for your words and professional response. You may be my next victim. (tuner) just kidding I wouldn't make you deal with me, lol!
But when you do an e tune what makes you say ok I can help you or say your car is not ready. All in all whether your on a dyno or just looking at scanner info your still looking at the same basic data, right?
I would imagine a tuner could point out an issue by the data they veiw, correct? If there is a vacuum leak you notice an increase in added fuel on fuel trims or vise versa. If you have a leaking injector you would see fuel be taken away by the computer.
I do realize there maybe some varations due to upgrades or aftermarket parts, but a tuner should have an idea of what to expect with the mods given, right?
Example: I just put in 1000cc injectors, but I have a stock tune and I have a vacuum leak. Fuel trims are showing +15%. Would you be concerned with that addition if I didn't mention the vacuum leak?
The whole idea to this is to see if the e tuners are looking at this kind of info. And basing there tunes to just work around it or just saying, hey there is an issue with your car that you might not know about.
Also have you ever heard wastegate flutter caused by a cracked ringland? I was so weird, cause the car was making great power and I thought everything was going so well and then I noticed the wastegate flutter and the lack in power and that was my first sign of the issue.
