Vauxhall Astra VXR
Hey, I currently got an ITG panel filter installed, janspeed exhaust and decat. I'm on the waiting list for an angelworks inlet manifold and then I'll get it remapped when thats been fitted. I used to have a 1.2 Dynamique with a viper induction kit on and I loved it, made a nice noise and did make the car more responsive. I've read loads of bad reviews on here to do with the viper on 172's and 182's as it loses power compared to the standard air box. All these opinions seem to be from people without remaps. I was wanting to know if anyone has had a viper combined with a remap and what kind of performance gain you achieved if any. I read yozza seen a 13bhp gain once. Thanks.
