Hi own a vn v8 calais 320,000ks and have bought a vs ss series 3 ute with 130,000ks to replace the old girl. The calais is stock standard auto with just an after market muffler. The ute is auto with pacemaker extracters, 2.5" straight through exhaust, 70mm throttle body and greenfoam tune! After driving the calais all week and then jump into the ute i find it very lazy and dosent seem to pull like the old calais! should the ss ute go beter than the calais or are the vs series 3 a bit sluggish compared to the old vn's?
