I think it would be cool to learn the ins and outs of tuning but i bet zzp or intense could get you a decent mail order tune. Did you use the l32 cam? If so all that's really changing is your na block has more compression. I'd give John a call at intense. I bet he has done a dozen pcms with your exact setup. I'd guess the ss intercooler and headers a will allow you to run that 3.4 no problem.
