Are you referring to throttle blips that get ignored? For example, you attempt a blip to do a downshift and it literally does nothing and you end up putting your head in the windshield with a mismatched downshift. A lot of this has to do with the TIR (Transient Ignition Retard) which pulls timing when there are big RPM changes such as a gear change. Out of the box the car will audibly detonate if you do a rapid gear change. In 2017 they revised the TIR tables to combat this but at the same time they killed throttle response. The only solution I've found is to use the pre-2017 TIR tables but with E85. So I get good throttle response without the detonation on quick gear changes.


There is a thread around here somewhere where someone was trying to come up with new TIR tables that were the best of both worlds but in the end I think they gave up. You say you don't care about E85 but it really does transform this car. The inconsistent throttle response completely vanishes and you no longer have that disconnected feeling.
