Tuning And Nitrous Question!
I have all the mods in the sig. Still have the cam and tuning. I have recently bought a Nitrous Express wet kit. I have already changed the plugs to some NGK TR6's. My main concern will be the timing advance. I have raised the compression a little bit since the heads were resurfaced during a rebuild. I have a PCM4Less tune on the car and I believe that his tunes advance timing from stock. Will I be alright to run the car with a 150 shot. The air fuel ratio is perfect on a Wide Band O2 reading. I was told around 100 shot but I may need to take some timing out for the 150. The NX kit says that you may have to take out timing for the 150 shot. I have heard alot of different ideas and wanted your guys opinions.
Thanks In Advance

Your tuning won't know when you're running nitrous or not. The work around is to buy an aftermarket ignition box that has a timing retard feature. You can then adjust the timing and have it only retard timing when the nitrous is activated. You will of course adjust your air/fuel ratio by changing your jet sizes. The recommended jets are based on a stock engine and PCM.

Well I was wondering if it would be alright to spray the 150 shot on the tuned car. I know it was tuned for an all motor application so do I need to get it re-tuned. How much would be considered safe with a little higher compression and a tune?

You shouldn't need to change the tune. The nitrous and fuel solenoids will add the appropriate mixtures of gas and well... "gas", and a retard (duh!) box will pull a user determined amount of timing from the motor.
How much did you have the heads surfaced? I doubt it was enough to affect the compression very much.
