hey guys, my vp wagon 5litre auto did a 15.5 @ 86mph the other day im a lil worried about the mph my 60ft was 2.372 and when it was stock no mods it ran a 16 @ 86mph... since that run i've got a fully rebuilt auto with stage 2 shift kit bigger boost valve and corvette servo also pacers and 2 1/2inch system. any ideas with why the low mph? its going in monday for a tune... just thought there might be a gremlin somewhere i can find

Get a compression test on it and check that fuel regulator. I bet it would be down 40rwkw on what it should be. I'd even say you would be very lucky to pull 110rwkw on a dyno with an 86mph terminal speed might even be around 100. So there's definatly a problem somewhere. Anyway lets hope it's something simple and then you have instant go fast when it's fixed
