I have a 2020 Veloster turbo DCT. I have several other cars so the mods to the Veloster are slow in coming. So far I have added lightweight 18x8 Motegi Lite wheels and sticky A052 tires. Saved 4 pounds per wheel. Also have installed HKS plugs and a Lap 3 Pro Tuner. I currently have it set on the 91-92 octane map. Noticeable gains with the Lap 3, now my problem is pronounced wheel hop. I must comment on Lap 3's customer service, I am 64 years old and have owned approximately 35 cars, 30 motorcycles and 3 aircraft, I am constantly ordering aftermarket parts but rarely have I experienced the immediate and tolerant customer service Lap 3 provides.
