hi all i have owned my sup for 1 week when i 1st got the car i hit 145 and after a few days i was only hitting 120 and the car would hold back on full revs i was at the dyno day today and after having a good time there and getting a 301bhp on my stock ttjspec i filled up at the bp petrol station and my sup is like a new car the drive home was so much fun its hard to imagine that the fuel can make so much difference i just cant stop driving it i get around 160 what top speeds do other tt j spec hit and would it be worth my while getting a decat ?????????
i plan on having a new dyno done with bp petrol to see what the difference it makes if any
