Boost not hitting targets, spiking after letting off throttle

Es_wetto · 12-13-2022, 04:25 PM

Currently getting revisions done with Doc vu, and I personally think my datalog looks fishy, I have asked a few people and they say not to stress, is this something maybe related to me only being on 3rd revision of the tune? Or is there a larger problem that needs to be addressed? Currently have mad charge pipes, dv+, cts boss turbo kit, catless dp, 3.5bar map, dorch stage 2, xhp stage 2 trans tunes, and cts inlet, could anyone check this out and let me know?

Your wastegate duty cycle looks a bit high for that little boost. I would do a smoke test and check the vehicle for leaks.

You have a boost leak. Boost spike on throttle closure is completely normal.
