Nothing much that would add that much performance. I have a
BMS intake, OCC, HKS spark plugs, and muffler delete. I have 2021
G70 I think it weighs about 100 pounds less than a fully loaded Stinger. I grabbed all the goodies =).
The intake has poor heat shielding, muffler delete saved some weight (30lbs?). I like the whoosh sound from BMS, I think it sounds the best, but I would put the gains at net zero at best. I have Michelin Primacy all-season tires and the factory 19 inch wheels. Someone on the
Genesis forum weighed the wheels, I think it was 32lbs each

. Stock intercooler is still installed and I can tell I'm losing power up top because of it. Hoping to remedy that with Mishimoto soon, was gonna go Wagner but idk. Didn't feel 100% (personal preference, no hard data).
Car runs just pump gas. I have 93 octane, but no wmi or cpi installed yet. I am 1.4 bar on my ECU, my TCU is set to -5%, so there's room for a better time which I should get once my retune is complete.
Dragy PB's so far (not sure if it matters, but all times are with spare tire installed):
0-60 3.49s
1/8th 7.50
1/4mi 11.66
I'll get some comparison data once the weather warms here. I live in New England so the it's tough to get runs sometimes due to temps and snow. It was 55 degrees Saturday, and then 21 degrees the next. Smh.
