Nitrous Tune ???
Nitrous Tune ??? Whats the most accurate way to tune and make sure its a safe one on newer EFI vehicles ? Read the plugs... or watch the AFR's as you make a pass. If so, what kind of numbers are you loooking for ? I Already have the right amount of timing taken out using the IAT on a switch. Thanks in advance. Sean

Good Luck!
150 shot i took out 6 degrees. Hit it a few times with the richest fuel jet suggested for the 150 and the plugs appeared to be slightly dark. Plan on going a little bigger and wanted to ask just in case there should be something else i should be looking at or looking for.
Do you have someone to tune your car for spray or log it while you do it?
What plugs are you running?
Spraying running to rich can harm your motor just as bad as going to lean.

I tune my car on a 200 shot. I dont read the plugs at all. I probably should, I know. I have 2 tunes, a motor tune and a nitrous tune. I run 22 degrees up top on the nitrous tune and I always log the wideband and my knock table. I have put a bunch of bottles through it on the 200. I guess to each his own, either way works as long as your careful and have a clue as to what your doing.
Its been said 1 million times... the knock sensors are useless for tunning nitrous. rich is not safe. and you have no idea if you have the right amount if timming out without looking at the plugs AND the fuel being close. Your methode of tunning is like throwing darts in the dark maybe its good maybe its not...

10 Camaros You Should Never Buy
NO.... not at all. lol. using 7's shooting 175.. taking away 6 degrees. ill make a pass.. kill it.. coast to a stop.. pull a front and rear on either side. They Look how a normal plug should look. Maybe slightly darker with a yellow tint to the electrode ??? i know, pics would be better. lol

Correct me if I'm wrong, but the timing mark is discoloration from the ground strap getting hot. When reading the ground strap, you start above the electrode and read toward the bend. You want the mark as close to the bend, but not into or past the bend on the ground strap.
