I have gotten my pcm for less tune. I am running a 5.3 Z motor w/ cam.

I am only getting 10 degrees max advance. I bought methanol injection so I could run more timing being that boost is maxed out w/ 2.9 pulley. I told brian about the meth but 10 seems low. I get 0 kr w/ out any injection.
i have the snow system the pump can go up to 140 psi, and i have 675 nozzle if 325 is not enough. need some help please.

thanks.

 

you have no tuning software to make the adjustment? just pcmforless? I ask because the most common answer is going to be it is different for each setup/truck(even with the same setups) so you should go up in increments of 2 or 3* at a time until you get kr, then back off. Same goes for when you get the injection...however the injection will help keep temperatures down so that your iat correction table won't "take" timing, not so much help you run more timing that what already is your max timing.
