cheers lads, n martin, it happens when in 3rd or above and over 4000rpm wen boostin. im runnin beige injectors, t3,- 31 actutor, larger intercooler, n wat should b a 195 bluchip. itll pink 1st then bak off to half bar. ive just looked n not sure if it could be this but wen my m8 fitted the -31, he removed the diy boost valve n fitted a amal valve off a s2. shouldnt it b wired up 2 the ecu?? its a simple fix coz still got old amal plug underbonnet so im gonna plug it up properly. its just weird how it knocks itself into safty mode (0.5bar) wen u get it to pink. got a new pump from motorsport developements today so gonna fit that soon as. its bafflein me dude n im runnin outta cash n knowledge =( i bought her last xmas n shes had 2 FULL rebuilds; loads new upgrades n still not runnin rite. its my 1st rst n i feel like givin up??
