JB's Journey with JBR and Stratified

I would say it is complete. I am in the writeup process. It is taking longer than expected because of my workload being back at school. I am going to finish the writeup as soon as possible.

Am I the only one still waiting on the the verdict for this?

No you are not. I really would like to know how this pans out. I do like the stratified tunes and will consider sticking with them based on his findings.

@jbmazda6 Stop masturbating long enough to give everyone updates

what happened? THE WORLD WANTS RESULTS

[jbmazda6]

Ok, so I finally found some documents to hold you guys over. I am extremely sorry for it taking this long. My computer is currently broken and has all the documents from this on it. Hopefully it will be fixed soon. When I get all the data back I will post data logs of everything as well as a comparison between vdyno and an actual dyno.

I did not get to complete phase 6 (the phase I was really hoping to complete) but I will hopefully get to do it this spring or summer.

There were some unexpected results but I believe that this was due to limited tuning time as well as the hot weather and crap gas in Dallas.

I would like to thank Jamie and Alex again for helping me with this. They are both very great people and I highly suggest buying their products. I wouldn't do it any other way if I were to do this all over again. Hopefully they can use these results for further development of their products and skills.

If there are any questions please let me know.

Documents are in the original post..just fyi

Awesome comparo. Phase 5 (DP installed) really shows improvements throughout the power band, with both max and average numbers higher than either phase 3 or 4. I've seen conflicting reports on the effectiveness of a DP, so this is encouraging.

The question at hand is if the roughly 10hp increase is worth the headache that is a downpipe install.

I wish JB had done a comparison with just a testpipe and then full downpipe to see what the true difference is.

I would have if I owned a money tree lol $70 a dyno adds up quick. I think i remember me and alex stating that the numbers would/should be about the same with just a test pipe on a k04. The downpipe i got has a cat in it as well. I personally believe it was worth it.. and as weird as this sounds the one thing i really liked about it is that some drone actually went away so the cars quieter at higher speeds.

This is true... The DP is truly a nightmare job. Hey @jbmazda6; what DP did you install?

I installed a cpe full length downpipe and to be honest it wasnt that bad compared to other things ive done on this car. Having someone around who has done it before would be a big help.. and having the right tools is a must. If i were to do it again i could probably do it by myself in 3 hours.

Does that 3 hour estimate include stopping to administer hand jobs?

I really want to see the difference between the 3.5'' and the 2.5'' intakes. My car could not break 290hp even on ethanol with the CAI.

After I installed the 3.5'' with 3bar and GFB BPV I'm now beginning to see 300hp on my logs.
