As requested from another thread. Major idle issues, poor driveability... basically I'm not sure what I had paid for. lol

Not the way I would do it. Spark, VE and other tables are rougher than I would like. There are difference of opinion on the IAT table, but I like them close to stock.

There is a huge spike in you Main VE table, Your spark tables need work, Your adaptive idle spark under speed has been zeroed out, and t is commanding 12.3 in PE mode.

It is things like this that made me go out and buy HP Tuners and learn to do this my self.

I think a title change is in order, or maybe a new thread to be made, then sticky it. That way it would be more dedicated to shit tunes, and if you ever get bored you can open a file and make a post explaining why something in that tune is bad. Might educate some noobs too!

this is one of the best threads I Have found on what not to do! I am a newb so I like seeing what is a NO NO keep up the good info guys. I know i appreciate it along with the other newbs.

The OE tune is an original file to use as comparison. There's 2 logs, one before, one after, of one specific change.

I would like some opinions on this one?

I'll post the file later, but last night I looked at a friend's truck that had a Bullydog on it. 2003 Sierra Crew Cab 4.8l, he'd complained about it not being real quick. Basically there were minimal changes, the timing table is horrendous. The best of all was the PE EQ was 35.28, I did a double take. Whenever it finally went into PE this piece was commanding a 0.41 literally. It's close to the one from a "speed shop" in California who helps with magazine writeups for Truckin that was a 0.62 EQ ratio. Awesome stuff...

Here is one from a shop in Dallas.

Stock bottom end 09 G8 with a TVS2300 running 5.5lbs of boost, Headers w/CATS, Small cam, and ported heads.

I like the PE enable and EQ ratios.

Same shop different car. This one is a 2010 Camaro with a TVS2300 Small blower cam and long tubes... At least this one doesnt stay in PE mode all the time.

Got another jewel. This is from a popular tuner.

I want sooooo bad to say who this is from. I've tuned several cars that this guy has tuned. They all look the same. Not only does he do what he does in the PCM, but all the CTS-Vs I'm tuning that he's tuned, he takes the SC bypass solenoid off and plugs the line!!

I'm not here to throw names around. Just showing some of the crap that gets passed off as "professional" tuning.

[DSteck]

For a site full of people doing their own tuning, knowing who did it won't change anything. I just happen to have gotten into it repeatedly with the individual that Ed posted about.

[Ben Charles]

Got a tune from a Individual who's been tuning for 25+ years for a 2006 C6 with a maggie at 9lbs of boost. Done a comparision to a stock 2006 vette and the MAF sensor wasn't even touched
