hi every one i have a 2000 c70 t5 i am wondering what tuning can be done to the t5 and what gains can be had, i dont want to go straight for a ecu, also what dump valve can be fitted if any and also am i right in thinking that you cant fit a bleed valve to this engine due to the air being metered.. cheers all, i look forwared to any replies

i have a baily dump valve on my t5 but if you go through don does a forge one that has the pipe work with it you will also need a recirc blanking plate don't get a bleed valve get a manual boost controller you will also need to fit a boost guage to set this up mines a 95 850 t5 recomended boost on that is 14 psi not sure what your max would be you will however get fuel cut at high boost without a chip/remap the difference is a hell of a lot though

Hi, Dare I say Stage 0 Tune-up/Service? Get the basics right and make sure they are really right. I would also include all rubber pipes and elbows etc Des. . . ;)
