What should my next go fast mod be ? I have a 2004 impala SS. First off I'll be waiting for my tranny to grenade before saving up for one from triple edge. I have two other vehicles doo down time is no big deal. Now my current mods are 3.5 mps, wizaired via, 180 tstat, spotlight 104's mail order tune from overkill. 3" zzp catted downpipe, zzp plog. I was thinking rockers but not sure which ones and where to get them. Maybe moded 1.9's ? No cam for me. Then i want to get a full size intercooler after.
