Not sure that this will be the case for all 08's but here are the number my 08 FFV put down on the dyno. Truck has had its 1st oil change at 3k and currently has 5k. These are my 3 dynos. 1st dyno is 2008 FFV with the addition of the Volant intake and exhaust and airaid tb spacer. 2nd is a dyno of my stock 06 FFV on the same dyno. 3rd is on the same dyno with the volant intake/exhaust and tb spacer and timing advance on my 06 FFV. There was a spike in the graph from the truck shifting, but the numbers are 292hp and 368lb ft. Please note the a/f ratios in each graph. What does this mean? Well it looks as if Nissan is either making the engine run extremely rich at WOT, or this combo is far from ideal on the 08's. I'm likely going back to stock and back to the dyno and see the results. If the numbers are better stock, Volant can expect a less than pleasant call.
