Totally fucked me over. Rob said he could fit an Apexi boost controller & new actuator to my Focus RS. Got there at 9;00 am, left at 7:30pm with a car that wouldn't boost properly. At that point he said he'd never done an Apexi before.

Next day checked actuator, one nut was half done up down the stud, t'other was just done up enough to engage with the shakeproof bit, hence the boost being all over the place as the actuator body was moving by about 10-15mm. Fixed that which made a massive improvement.

Took it to APT who are experienced with Apexi fitment due to their dealings with Jap stuff. Didnt tell 'em who fitted it and asked for their opinion. Their reply was it is the "worst fitment of an Apexi" they had seen. They completely removed it and re-fitted for me for a damn site less than SCC.

Just my experience tbh.
