Question: Hi Alan, my standard Xr4x4 TT has started running poorly. It runs as if it is overfueling like having a choke full on then it clears for a few seconds before doing it again. I have not done anything to it or have any other problems. Can you advise? Many thanks, Gez.
Answer: There's nothing easy about the K Jetronic system if it starts to play up! Your best bet is to find someone with a rolling road, and hope they have the knowledge to get at it properly. One possibility before you do that, is to check that all the boost hoses are perfect, as any leaks between the turbo and the throttle body will cause a very rich mixture. On the off chance that it's actually lean, check the pipe from the air flow metering unit to the turbo intake.

Question: Hi Alan, Having had a bit of an accident last friday night i need to buy a new car. now as before ive looked at Vectra GSI\'s, Subarus (insurance a bit steep at the moment) and other cars. Im looking at a peugeot 306 GTI-6 and was wondering what performance gains i could achieve from tuning one of these? I\'d be looking at a rolling road, chip and a filter swap. Would there be much BHP gain from the orignal 167bhp? Thanks Gav
Answer: Hi.. Air filter chip and exhaust is all I'd do with it. I doubt you'd gain very much considering the car is well sorted already, but the midrange would be improved, with probably 5 bhp or so at the top end, due to the better flowing filter.

Question: Hi there ive got a 1997 subaru sti type r just wondering what plugs to use? Im thinking about ordering some hks ones Thanks
Answer: Hi Steve- No harm in it! Generally, unless you are using serious boost, we'd stick with NGK PFR7B plugs, gapped at .9mm dropping to .7mm over 1.1 bar.

Question: Hi Alan,I've got a uk turbo 1998 I want more power but want to keep it reliable i.e dont wana wreck it cos its my work horse! I've got 3 grand is that enough to get it to a state of tune where I won't wreck the box and clutch?and can run it safely and won't destroy the engine internals?cos it isnt an sti,so does that mean the engine and running gear are weaker?any advice would be much appreciated.cheers
Answer: Hi Peter. If everything is in good order the engine will take up to 350 bhp easily. The RPM is limited by the spec, but not the BHP. 3000 is a good enough budget to cover a decent conversion, certainly over 300 bhp. If you'd like to know more, ring Martyn on 01752 345880 office hours to discuss.
