hi guys, im confused so need some advice again. i'm ready for bookin my FRST in for a rollin rd/set up, so just for added peace of mind i had her diagnosed this morning for any faults and she read 3 faults. 2 were ecu related but wayne @ the garage said dont worry bout these coz its just his machine picking up my chip. if he tested again with chip out he said the faults would go so im happy there but hears y im confused. 3rd fault was wastegate celonoid faulty/vacuum (amal valve). im running a bleed valve(not my choice) so there is no amal valve. he said thats y its reading faulty coz my connectors r still there for amal but there not connected to ote. few wks back, we took bleed valve off n fitted a S2 amal valve but that lost voltage somewear from connection to actual valve so it didnt work. we fitted the bleed valve back on. now, waynes sayin it wouldnt work and it would of lost voltage coz i need the PROPER FRST amal, not a ERST 1. is he right? also i found a bloke whos breakin a FRST so i asked him for the amal valve. HE's sayin i need a S2 amal if im runninT3 ( i am ) or the FRST if im T2. so who's right??? or do i just stick with the bleed valve coz ive no idea now which 1 i need. ive wasted enough money now so i just want her right
