Fuel is garbage.

I don't know anything about that turbo though so I can't comment on boost and timing targets for pump gas.. but that fuel is garbage. You either need better quality fuel or that tune needs to be scaled back some.

What intercooler are you running?

What was the outside temps during this run?

Edit: Maybe you could add more meth?

Maybe it's not just the fuel but the plugs and gap you're using.

Hi - I also live in China...

I dont agree that the fuel is shit. Car is achieving 8° timing @ 20.5psi @ 6300rpm. Ign target is just too high hence all the correction. A good tuner would solve the problem and lower boost or timing. What is your water/meth %? Also, stop gapping your plugs. The 97506 are OK but run them at factory 0.8mm gap.

I see just now you are running 95RON. No 98 from 中国石化 where you live?

Where did you buy the SS-Performance turbo?

Since I want to go to 500whp, I don't want to lower boost and ign. No problem with this turbo, they told me it can go to 550whp at 25psi. I am in rural China and I use ethanol instead of methanol. 75% ethanol and 25% water. Do spark plugs need to be adjusted?thanks

You have ethanol. Problem solved! Put that in the tank mixed with 95 Yes, I suggest you gap your plugs to 0.8mm as they come from the factory.

2/3 95RON 1/3 E85 = you are flying Remember to get a custom tune for this!!!
