Had my MY99 Remapped few weeks back with simtek was awesome, but for a few days now its down on power, noticed a fumey/petrol smell while driving, worried that when i fitted the VF29 Turbo i forgot to put one of the brackets that hold it to the block and may have damaged the uppipe, is this likely, checked injectors and no leaks no water in oil idles very smooth, since getting it mapped MPG has increased

 

Sorry not to sure what you mean ,as when you fitted your turbo to your car,i am presuming you bolted it on to uppipe with 3 x 14 mm bolts ,then bolted your cat/decat on to the exhaust housing with 3 studs and 2 nuts & bolts .

 

Yes done all that but the uppipe has brackets that hold it to the block i forgot to put one on

 

do u think u have split a weld on the uppipe? does it sound like its blowing?

 

Doesnt sound like its blowing, could my low power be this damp horrible weather up here in scotland

 

dont think so mate. how old is your fuel? is the power definatley noticable?

 

Yes as the clutch was slipping with so much power, now noticable drop and clutch doesnt slip

 

Did you fit the turbo after re-map?

 

is it still boosting same. if not may have boost leak

 

Not really,cooler temps mean cooler air into turbo & intercooler,so should be no drop in power ,if anything a slight increase should be noticed,
