i have a wet 50 shot on a NX kit on my 4th gen jdm h22a prelude I/h/e i also have a chiped ecu the guy before me ordered from pharble.net .....WILL I be ok without touching the timing and just running 2 step colder plugs ??? or will i need to retard it ?

 

I'd pull a degree or 2 just to be safe.

 

you dont need to pull timing, but its a good idea to keep your motor from detonating

 

I usually go with 2-3 degrees per 50hp of nitrous, just to be safe. but nothing beats tuning it on a dyno. that way you can find out EXACTLY what's best for your setup.
