thanks lads.just wanted to know. before i get it mapped. not many mods at all tbh. front mount full exhaust downpipe running 7/8 psi.. but i do think at somtime in its life that its had a bigger turbo on? cause when i got the car it had a paddle clutch in it. and it was slipping and with the current mods i have now.i doubt they would make the clutch slip.

i was saying the same thing at first,,,,,,but could be a number of reasons including how the test was done, the type of compression tester, if the tester is good, etc.etc....

i know we accustomed to hearing somewhere between 150-180cc per cylinder

Different compression testers give different readings as long as the readings are similar you have nothing to worry about. It is very unlikely there is anything wrong with the compression accross all 4 cylinders.
