high rpm bog?

[hendrixvodu]

Do you have a check engine light wired up? And do you have your speed sensor hooked up?

the m10's didnt come with cel so i wasnt really sure how to wire it, i have a late model m20 cluster now...and what do you mean by speed sensor ?

having an issue with the car, has a bogging feeling at high rpms as if it hits a speed limiter almost... its also random and sometimes it will not do it. changed the maf, filter and plugs...has perfect idle and start, runs great besides.. car is an 84 318i with m50tu from a 95 e36...it has a noisy inline pump im wondering if that could be the issue? ...any info would help, thanks guyzzzz
