Message: <blockquote data-quote="ravingill" data-source="post: 1063695696" data-attributes="member: 30261">Hye guys , well i recently purchased a BMW 525i (M) with a BOT kit , i have changed to bigger intercooler , redid the intercooler piping , redid oil piping , added a scavenge pump (turbo oil return pump) , added a BOV to my turbo system and also serviced my TURBO at Tong turbo. Now , when i drive the car around normally , it is fine i can rev up nicely and all. Problem is when i floor the pedal , in other words , heavy acceleration , after about 4000-5000rpm , my car jerks , rpm does not climb and BOV just goes (pshh pshhh pshhhhhh) until i release the accelerater, it only happens when i floor the pedal or accelerate rapidly. Why is this happening ?? Any idea and info would be really great, also to add the car has no management system , i am planning to get e-manage ultimate soon to perfect the tuning system.Car is using BMW 525i original engine , 5 speed manual transmission and has a Turbo kit</blockquote>
