I have an A4 1.8 T sport '97 (non-drive by wire). What should the car boost to as standard? What is the safe limit for a K03 to boost too? Has anyone fitted a manual boost controller to these. Would/wouldn't you recommend this route. The reason i ask as that i will only make 30 bhp if i get the car chipped. So i was thinking of going manual boost control way, & turning it up a bit then just leaving it. Can anyone highlight any problems this may cause?
