So today went to the Shop, installed the new Active Autowerk Highflow DP, car got flashed then put on the dyno for a custom conservative tune for daily usage and Track day abuse. On a Mustang Dyno made 383whp and 433TQ.
As I thanked everyone and driving home the throttle felt a bit laggy, I got on it..some delay then hit hard ...pulling then back to slight hesitation. Did this 4 more times then got a Pop up "Drive train Malfunction" then car felt slower before I put the DP on.

Contacted my tuner and he was shocked because everything ran Kosher on the DYNO, hes tuned dozens of MKV Supra's with higher numbers/aggressive tunes. Now Im home, livid bcause I spent 7 hours at the shop and now this.

Anyone else experience this after their dyno run?​

Definitely tune related issue since you mentioned is custom and not OTS

Go back to the tuner.. Car should feel much faster across the rev range and no errors messages should pop up like that
