Buckling concerns on turbo
Hey everyone. I have a jdl turbo that was installed about a month ago tuned by James @ HRI(I believe he's on vacation or something). Anyhow, at around 4k rpm it feels like theres intermittent fuel cutting cruising at that rpm / 80mph. It does this on occassion accelerating as well. I took a log of it if anybody wants to chime in.
Parts: 1050x injectors dw265lph fuel pump delicious flex fuel kit+ with upgrade 2867r turbo w/ upgraded intercooler from jdl jdl catchcan 3" overpipe / frontpipe from jdl w/ stock catback https://ufile.io/5qdf04nn Is the .csv file I sent him the log already but he hasn't gotten back to me yet so just wanted to see if anyone wants to chime in. |

https://jdlautodesign.net/shop/ft86-...turbo-system/# If we take a look at the tube, it has a nipple on it. Does that need to be covered? |

Fueling seems strange 15% accelerator and target afr 15. Fuel trims like tom brz said seem off up to -30.
If your sure no leaks, check no oil on maf sensor. Manifold pressurecseems strange as well assume its absolute . Reads below 14 psi atmospheric so its producing no boost at 4000 rpm with 15-20% accelerator. Check your di computer is bolted up tight all three bolts Check map sensor Difficuult to tell as we dont know if tune is maf or speed density or hybrid |

heres idle, also just went outside to check for any leaks. No leaks. MAF sensor bolted on properly. Could the catchcan be the issue? Sorry, what's a di computer? |

Where is that hose coming from? If that's a pcv catchcan, your feed from the engine should be going to the top port.
Did you clamp down the hoses UNDER the intake manifold? Here's a glimpse of mine in the middle, you can see a worm clamp on one of the 3 hoses. |
