Mercedes c63s AMG vs BMW 435 !
On 17.5 psi, going to raise boost a couple psi to 19 (max), to even it out a bit more next time.
MODS – The 435i has stock turbo, JB4 tune, ER downpipe, intake, 6 gallons e85, on hankook tires.
The AMG had the lightweight performance seats on Michelin Pilot Cup tires.
I expected the 63s to be a lot closer to the zcp m3/m4’s I’ve run, but these v8 biturbos are a completely different monster. He got me by half a car on all the runs we did.
