yes it voids the warranty and I doubt the dealer will do it for you. They will probably look at you like if you were nuts as if its not in the gm performance catalog they have no idea it exists and it cant be done.

I hope to be getting my car tuned soon. Just did all the mods in my sig. now if the car reads 40% i know I didnt seat it right. I just put the pin in and tried to some what lightly pull it out. it stayed in place. Thanks

My wife's Dart has 160hp (I think) and averages 26-27mpg. Losing 30% gas mileage and gaining almost 3x the power is pretty impressive.

20mpg and a low 12 second 1/4 is EXTREMELY impressive. Almost no other manufacture can achieve this.

I just installed the E85 unit and the white wire. I have also installed the aeroforce gauge and it is reading the alcohol at 0 percent. Can you read the percent without a tune or do I have to turn it on in the ecu before I can even read the alcohol percent? Next is the wideband... that should be fun....

Thanks Jwdominick that is what I thought ...

So my question is, is it worth it to buy HP Tuners outright or just take it in for tunes? Im a really DIY guy and want to learn how to tune the car. I did the same with overclocking my pc and while I understand they are not the same, it isnt very easy to keep a 5930k stable at 4.7ghz on 1.35v. Same with my old 980ti and 1080ti. I am just really scared on putting in a tune from the forums and something breaking. Also will the price for a custom tune be the same or is a HP Tuners credit price reduced from the price of a custom dyno tune? Im not really sure how this whole credits thing works. Will I use a credit tuning it myself in my garage? Very confusing system. Plus wth is the NGauge? Is it just a HP Tuners thing built into a gauge? Does that need credits aswell? Does the pro vs normal? Jesus their website doesnt explain sh*t....

you have to turn the sensor on in the PCM...it's set to virtual by default.

HP tuners is worth it's weight in gold. I have tuned several vehicles with it...love it! The A8 transmission is sooooo much better with a proper tune. It gets a lot of bad press and that is all due to GM's crappy tuning...it really hinders the driving experience that everybody should be experiencing with the A8.

well i dont do my own tuning but heres what I know about it. The HP pro cost $500 and come with 8 credits. I believe that's enough to tune 2 cars if manual. Then you would need a wideband o2 to add to it and those are $300 i believe. so you will have $800 into it and have to learn how to use it or you can pay $450 for a dyno tune by a pro and $150 for retunes.
You dont have to use a wide band but to get the best dialed in tune you will. Dyno tuners use wide bands. If you dont want to use a wide band you might as well get a emailed tune and tuner for $400 with free retunes.

Hmmm since I'm going to get a 1LE its a manual so no credits needed for the trans. The 8 credits how far will that get me? Every time I get a tune that is a few credits right? Also I did not know that retunes are less. Like if I get a tune for E85, and bolt ons and later add a supercharger the tune is less? Or is a completely new tune so ~$450 again? Yeah I think Ill be getting the AEM wideband or can the NGauge do it aswell? An emailed tunes get free retunes? Damn who is offering that!

Yeah I think that Ill be still getting a 1LE. Even though it will be my DD, the A8 I test drove was not nearly as smooth as the autos I am used to in Lexus and Merc.

The same tricks that worked on ls stuff does work here and it's a more complex system to learn. Not something I'd personally suggest a novice to dabble with without much guidance.

I've seen some videos of the tables and yeah doesnt look like something I would just dive into without some guidance. Doesn't HPTuners offer classes or something online to learn how to tune? But if I remember they were quite expensive so might as well get a custom tune to save me the time and trouble.

most of the email tune guys offer free retunes. The credits are to tune a Vin. no limits on how many times you retune it. Thats why the dyno tuners charge less for retunes.

Which one would you recommend? My thinking is that a dyno tune will be more comprehensive than a emailed tune, but there aren't many shops in my area skilled in the Gen V. For an emailed tune do they send me a preliminary tune and then I do some logs driving around and then they correct or is it one and done for any altitude etc? Sorry for asking so many questions, just want whats best for my car lol.
