I was wondering if anyone has the zzperformance.com custom computer? and how much of an improvement it makes. thanks!

not many people run the zzp pcm here, mostly INTENSE you will feed a big difference, mostly cuz of the higher shift points

as far as i know though, the zzp one is $20 cheaper

that or one of the others that are aval. not trying to turn this into a who is better then who. but use the search and read about them all. but its deff a great starting point. along with air intake and exhust. then mod from there.... till you get to the point of no return. then your wife makes you sleep in you car since you LOVE it so much and you spend more time with your car then you do with her.... but after all, we all love BONNIE around here. RIGHT???

lmao

When it comes to Bonnevilles, ZZP does not have the experience or interest that INTENSE has.

For that reason alone, my personal choice would be the INTENSE PCM.
