Yip it's a bit deeper, on down shift. but also sportier on wide open throttle, plus I gained about 10hp odd with the decat down pipe......
Are you going to decat the other cat aswell? As far as I know, the GTI has two catalytic converters.
Not as far as I know. It's only got the one cat thats in the down pipe....
the colour coded rear valance looks great
a 5dr pog.... NICE!!!

Larry, the car looks great. Love the wheels too.
Have you tried octane booster? REVO Stage 2 would probably prefer having 98 rather than 95 ron.
Can you recall any torque figures from other cars on the same day? how hot was it?
I was running REVO Stage 1 with down pipe and PD160 intake - and was running 183hp at wheels (after bit of heat soak as my car was the 1st one on dyno and there were setting to make sure things were okay) with 17" heavy RS4 replica wheels / it was 22 degrees that day.
I now have REVO Stage 2 / Forge 007 spring strength also increased / 4bar / will get new spark plugs next week - I am hoping to get 195hp at wheels. I have also returned to my original wheels as they are lighter.
Maybe next dyno, try better fuel / and check what the peak boost was at? I also have a 4 door - I love it.
06 Polo GTI - REVO Stage 2 = 140kw @ wheels.
06 Golf GTI - Bluefin Stage 1 blacked out with ED30 theme, leather, xenon, etc.
