I actually like to see more like 11.8 to 12.0 AFR on the spray. Now N/A yeah, 12.5-12.6 WOT. But he's right, the stock tune is a little rich to begin with, hower you should always check it with a wideband to see what your AFR is when spraying. With a wet shot, you can adjust the AFR by switching jets around.

11.7 on spray. 12.5 is too lean

if thats how you want yours thats fine. and it may be safer on a stock motor to be that rich. but when it come to tuning my tuner is excellent and has many hours of tuning under his belt. my engine is forged and he has mine tuned at exactly 12.5 to 1 because that is where it should be. on a non loaded dino it will read richer though so dont let that fool you.

13.7 on motor and 12.5 on spray

I would set it up with a wide open throttle switch and an arming switch. That way you will only have to mess with one switch inside the car. Arm it then when your wide open you will spray.

But i plan on still running my stock 18s with 245 Falken Azenis, so i plan on having the shot activate in third gear.

Will i hook in third with that setup and also is there any way that with a more aggressive tire, say 17s and 275s, i will be able to hook in second?
275-40/17 Mickey Thompson ET Street's. I have them.... They are unbelievable. But i dont even spin in 1st anymore...
