Nitrous Tune???

RE: Nitrous Tune???
cant run race gas with the cats still on and will also kill your O2 sensors. colder plugs +1 HTO are the way to go and i correct me if im wrong but with the 05+ stangs you need a tune over a 50-75 shot

RE: Nitrous Tune???
For a 75 shot the reg tune will be fine. just make sure you use 91+ GAS.
HIGHER then a 75 you will need new plugs, and I run my 87 tune with 91 gas. 100 shot no problems. No timing changes or anything.
If you go higher then a 100 shot I would get a tune for that. I use the 125 shot.To be safe I ran my 89 tune with 4degree's timing taken out and 100 octane unleaded gas, I have no cats but its unleaded if I did have them. With the race gas you could get away with timing but didnt want to blow my motor and wanted to be safe for sure so i took out the 4degrees. I could probably run the 91 tune with just the gas and be safe, but till i get on the dyno, I wont know for sure.
anything over 125I would use a boost a pump inline. Our cars love the nitrous. a zex 125 is like a 100 shot to the wheels. So with that and other mods, you should be about 380+rwhp
Most SC guys are about 430RWHP so being close to the 400 should be really safe.
happy squeezing.

you can put the 75 shot on and be just fine, but you will get better performance out of it with a dyno tune. I just switched mine to the 125 shot and put it on the dyno. they pills that are set up for it will cause it to actually be rich to be on the safe side. I make 35 more hp by running the 125 nos jet and the 100 shot fuel jet because it puts my a/f right where it needs to be, butthere is no way I would do that without a wideband a/f meter or a dyno tune. by the way, I just pulled 11.30s with the 125 shot this past weekend, thanks to the tune and some cooler temps

Nitrous likes retarted timing...I'd dyno it to clean up your stock ecu and retart the timing for optimal tune. Run your sct for the no2 and return it to you daily tune for other applications
