get tuner, get meth, buy real meth, mix it 50/50 with distilled water. i bet you could run a 3.2 with meth and nothing else, buy a wideband and a tuner. 3.2 pulley is where stock injectors are about maxed out.
as far as the tuning, you need to pull fuel from the maf to make the afr say 12.6 ish on the wb, then spray the meth, it will make up the afr by at least a point, your goal should be 11.5 ish, engine will feel its strongest on that afr, 10's it will dog, 12's it will likely knock. you lower the timing while doing this tuning to avoid kr. once the target afr is met spraying the meth, you can start to turn up the timing.
this is mine. i got a load of bolts on, 42 injectors, gen 5 N* with a 3.0 pulley cause the 2.8 maxed out my injectors, yt 1.95 rockers, ported heads, na bottom end headers, fsic and aem meth kit. its a progressive controller, meaning it starts to spray at 5 psi then sprays max at 10. i make 13 ish. start and max are fully adjustable in the car. so if you stay out of boost aka drive it normal the meth will last. but if your wot all the time you'll be refilling the tank daily lol
