- VY SV8 HBD---mmmm LS1
No, you don't need any add-ons to get some extra power, since the standard V8 is tuned quite poorly. I'm not sure if this is a deliberate marketing strategy to keep the "halo cars" significantly faster, or just "insurance" against abuse and potential breakages. If course, if you do have some mods done, you can get more benefit from the mods by having the engine re-tuned.
My VY2 SV8 is totally stock, no air filter, muffler change or even a sticker. It was dynoed stock at 240rwhp. After a tune using HP Tuners LS1 Edit(?) software it made 270rwhp. This is not a aggresive or dangerous tune - you'd never know the difference during the daily drive. Gains were across the entire rev range but most significant in the 4000-6000 rev range. I also had the speedo recalibrated and the auto shift points tweaked.
hey mate notice any changes in petrol
