mine smokes a bit when pedal is just over half way, as you have SS intercooler and cat bypass already yours should not be as smokey as mine. Guy at Jabba said they help to clean it up a bit. its fun when you get motorbikes tailgating you to overtake just floor it and they eat diesel fumes lmao.
But i managed to worm my way out of work, go to the garage where it was being fitted and do it myself! Got finished at 7 o clock tonight. 

The back end of the car, the first 3 letters on the number plate are unreadable. And i've done 50-60 miles? Not even giving it that much stick.
So yeh - going back tomorrow! As i said - as Chris!
