Our car's are made to run on 87 stock, obviously. Like VCS said that is very unusual to have it knock. Maybe you had bad gas. Maybe whoever did the tune didn't know exactly what they were doing - like trying to get too much performance from too little octane. anything v6 tuners = Justin @ VMP ftw!!!

 

yea justin def is the best v6 tuner

 

Yea, i mean if I have the stock tune on there then 87 runs just fine, no problem. just when i load the 87 performance tune, i get a ton of knock. perhaps i'll contact justin to see if he can help me out. thx fellas.
