    Low boost and exhaust pops

    Had the car set up last week to run BPU.

    Has been running spot on.

    This morning was driving fine but this afternoon had an issue.

    Car will only boost between 15 and 15.8psi and I get a load of pops from the exhaust.

    Anyone have any idea why this might be please so I can investigate.

    Thank you!

    Can't see any hoses off.

    Spoke to Lee (SRD) he says it sounds like a misfire.

    So pulled and swapped all spark plugs today. Coil pack clips are almost new.

    Went for a spin was fine for first couple of pulls then came back.

    Put boost controller into low boost mode and it was fine.

    So I'm thinking need new coilpacks.

    Took a trip to SRD today and they very kindly had a look at my car.

    They swapped the coilpacks I had just bought out for some new OEM ones and car runs perfectly.
