What does your timing look like currently? Your peak hp looks right but you could hit peak tq over 1k rpm earlier closer to where you hit peak boost. The stock turbo spools so early but you aren't seeing any of that power until waaay after it's running full blast is all i'm sayin.

this is after the intake install very happy again this is at 4,000 feet

so how do I fix those errors? Because whether I edit datalogs or not, it gives me the same errors

After fuel pump and throttle body upgrade. I will put the car back on the dyno dynamics after the holidays for a better comparison.

Whos your tuner? My build is almost the same as your minus the throttle body.

Hollywood FTW!! Cars feels so smooth from 1st through 6th. The power is dialed down to help the clutches from slipping less.

Brad, Thanks for some great software. Donation on the way!

Please excuse the attachments, it's the 1st time i've uploaded anything.

I wanted to compare before and after catback install dyno runs but I screwed up the before run and didn't get any log data at all. Nuffing. Nada.

1st chart is a graph of rpm vs time showing clutch slip

2nd chart
The red line has clutch slip @ about 3500rpm. The blue line is a modified csv file I created which has the rows of data deleted where slip occurred. I'm giving VD a smooth entry point for the 4000 rpm torque numbers. Notice there are much fewer data points between 3k and 4k on the blue line. 38F ambient, BTW. 340hp seems high.

3rd chart
Back to back runs the next day in Super Sport mode, 32F ambient. Data is consistent and believable, no clutch slip. Future runs will be in S-Sport. 309 and 313 hp. Notice that the boost curves overlap exactly.

4th chart
This shows the 340hp "fixed" clutch slip run vs the 313hp run from the day after with 6 degree cooler weather. At first I dismissed the difference as an error from the clutch slip...but look at the boost curves. The 340hp run has more boost from 4k to 7k rpm, which might account for the extra hp. I'm confused how the boost curve can change like this with no changes to the car and less hp in cooler weather.

Any ideas?

Installed my 3-port, and been fine tuning WGDC myself.

This is on 91 Octane, AZ Fry's Gas (lol). AFR's are high 10's-low 11's throughout the range.

Here is my 4th pull from an hour ago or so:



Touched up the small dip with 3% extra between 4-5.5k, added a .5% to 2k-3.5k, and will do another pull on my way home. Can't wait!
