The jb3 stage 1. I have a feeling I have a boost leak though
My second time at the tracks I hit the 13.69. After that I couldn't get it under 13.9 with a horrible trap speed. (before tune) Now with the jb3 I'm hitting 13.5x. After doing some data logs I've come to the conclusion that there has to be a leak some where since the car isn't holding boost in 3rd or 4th gear (map 0 and or map 1) My car seems to sound like it has a bov now as of late. Maybe the DV came lose somewhere. Or maybe my fuel pump is going. Like I said, I got the dreaded engine light at the tracks but I didn't try and drive it. I just turned the car on and off a few times and the light was gone. But I need to order the can tool to see what codes I have this way I can clear any that might be tune related.

Maybe this is why I'm not seeing good results at the tracks. Time to order the can tool and check things out.

Your hearing a bov noise while boosting or when you left off the throttle ? I have had the half engine light a bunch of times before as well as boost cut in 3rd and 4th gear. we switched jb3's and its been fine soo far. |

Do you drive with your windows up all the time?
I hear my Factory bov every time I switch gears and its pretty damn loud for stock and Sounds like a hks ssqv on low boost. Do you feel like it runs out of power as soon as you shift into 3rd or 4th? |

Yeah, logs show that I'm not holding boost. My 60 foot time and 330ft are fine. But my 1/8 mile times is where you can see that that it is slowing down a lot. And no, I think my windows are down more than they are ever up lol.

Also on a 1-2 shift feels like it loses power with the JB3, even with traction control disabled. Ive gotten the 1/2 engine light a few times on startup only and it went away as soon as I started driving. They werent fuel related codes however. |

On the blow off valve sound it is definitely going to be much louder at higher boost levels. I know at one point in the beta testing they lowered wastegate duty during the shifts as they felt they were starting to over power the factory DV with manual transmissions. If it's dropping boost let them know and perhaps they can make that user adjustable in the next firmware update. Mike Last edited by Mike@N54Tuning.com; 11-15-2010 at 10:28 PM.. |
