Yes 190 bhp is about right - i have the above mods (but with a sports cat and just a panel filter) on an AGU and got 189.6 bhp on the RR

You will get about 180 bhp.  in this heat .

been for the map first dyno test not mapped show 142.8 bhp  but the guy said as the car is 13 years old that was about rite?? anyway he took the ecu out done the chip then tested again this time 169.8 bhp  he said it should be around the 190 mark but was losing boost he could  see on the screen of the dyno that it was droping off. i have a blitz dump vavle on the cold side he tested again and said that dump valve was the prob it was losing boost out of that and that was losing me some bhp he also said it may be the spring in the dump vavle thats weak would this sound rite ?
he told me that the 18t's  dont like these type of dump valves but as mine is there to get the forge one with the stronger spring this should cure it

any help would be great  my boost is now around 17psi and holds at 14psi

Did they do a vag com check before loading the new map?

boost is about right but if it is a blow off valve then it will put your power down as it did on mine when it was on the rollers with my blow off valve custom cat back silicone tip weak actuator dodgy maf and a fooked pcv system i still managed to get 185bhp and 226 ft lb of torque and since replacing all the parts the difference is night and day you could feel the difference after the map but now its like a new map again main cause was the dv nick at r-tech changed it to show me and the figures changed instantly as the blow off valve was releasing the boost as opposed to recirculating it causing a loss in power

[wolfie1981]

do you think i would lose that much power from the dump valve?? i the valve was on the car when i bought it so i dont have any of the original pipe work to put it back to stock where could i get this lot from???
