Hi XRT SI yeah it's mapped by AMD in Kent was mapped before I picked it up I'd like to know what I'd get BHP I can achieve it's running the usual straight through exhaust Airtec stage 3 intercooler cias induction uprated plugs rs clutch and it's been on rollers giving 300hp 370lbft at AMD. But I have hybrid rs turbo big injectors (don't know what cc) plemdum uprated rs throttle body (70mm) rs cams so when all fitted will need re-mapping. Have been looking at A after market ECU but don't reallly know what to go for? Anyone know of any after market ECUs not revo mountune dreamsience ect.
