I had to remove data like specified lambda, time stamps, ect to get the text to fit in the first post

[na1mt]

Looks like you are making less power than what the stock tune calls for if you look at your boost log.

[4everRS]

Huh? Stock boost is about 1600 mbar

[na1mt]

Your specified boost levels are always higher than your actual....unless I am misinterpreting the chart.

......ok I'm lost.

[DHall1]

I got my popcorn.

[lswing]

Your specified boost levels are always higher than your actual....unless I am misinterpreting the chart.

Must be showing up wrong, specified is higher the whole time, and he's boosting about 15psi, stock is 8-9.

Looks good man! Nice low egts and high timing. I run a bit hotter, so i'm guessing your tune puts in a good amount of fuel. Could you do me a favor and log injector duty?

[lswing]

I got my popcorn.

Paypal me $20 and i'll add inflamatory info...

[4everRS]

There is a small area where actual is above in the mid 3k Rpm's. Most of the rest is withing 50 mbar. I know I have leaking IC's.

You see "actual mbar" pathetically taper away after about 5300 or so rpm. This is likely due to back pressure from the cats not allowing the turbos to spin faster. I want to remove them.

[4everRS]

. Could you do me a favor and log injector duty?sure. I can probably do it tomorrow sometime.

[na1mt]

I am just looking at the specified and it seems to usually be under boosting on your chart, no need for popcorn....I'm just trying to learn. Thank you for taking time to review my logs Dave.

[DHall1]

I hear a tape recorder

Ya. :)

So everyone knows. Dave said it was back pressure. I thought leaking IC's could be the cause of the taper.

[DHall1]

Yes, this is an example of a happy car with a great tune. Look at that timing map! Hot damn, that and the fueling are the prime reasons for the nice EGT levels. Viper tune is a good one for sure.

ok, I will paypal over some bucks.

[DHall1]

Yeah, 2% could be leaking out that intercooler. Its more that stage 2 tune calling for high boost levels at higher rpm. You got small snails and a restrictive turbine housing and cats 8 inches from the turbo. Never be able to maintain that boost to redline with the stock turbos. Gutted cats will help bring it up just a tad.
