Need abetter 1/4 time. need alittle help

So I have many many runs on my 1ss m6 and have not seen a 12 sec slip WTF (LOL). Car has seen 13.03 as the best pass and many other 13.0 passes. I have tryed many different styles of launching the car best 60 is 2.0.
Here are my mods xs full exhaust no cats,g5cr intake, trinty tune (canned).
I just seen that 91 octane may slow the car down It is all I have run in the car? Also have drs nitto 20in still 13.0 mostly run on street tires as I bracket race and can turn 13.30 easy on streets and shifting at 6k.

With DR's you should be in the 12's. 91 octane is fine for these cars. I would make sure that the canned tune is designed for 91 octane and not 93. Could be pulling some timing out if its a 93 tune? Do a fuse pull also and see if that helps. I'm sure there will be plenty of other things suggested here soon. Good luck!

What kind of 60' time are you running on the Nittos? If you can get below 1.99 you should see some 12's.

I have used them one time out a few passes 2.0 I ran about 24psi, I think that needs to go down maybe 19?

I'd try it out at 20psi if it were my car.

Post your best slip. I bet you still need to work on the front half.

Atco is a very fast track. I've heard of close to -1500 DA.
With good weather/track/launch, 12's should be a cinch.
Keep practicing and post some slips

Slips coming I will post all 13.0 slips this year. The funny thing is some are on the stock intake and some on the cai intake. I thought for sure I would see a change after that.
