bilal Member 14 Member For: 14y 10m 13d Gender: Male Location: Melbourne Posted 19/07/10 02:42 AM Share Posted 19/07/10 02:42 AM Hi guys, I'm new to the forums and am having a little trouble with my car.I have an 05 xr6 turbo mk11, 6 speed manual. I recently purchased an xcal 1 from a performance tuner who immorally sold me it with 2 generic tunes for my car. I was unaware of the fact that the xcal 1's can no longer be used to custom tune, so this box is useless to me and the dealer wants nothing to do with it and will not refund me. Apparently he has an old dongle with 200 tunes left on it and will continue to sell them on ebay until it runs out.When plugging it into my car, it runs really rough at about 3000 rpm+ and feels like it isnt getting enough fuel. It feels like its leaning and makes small vibration with a weird noise. However after having the 10psi generic tune running for less than 2 hours, as I went to take off, my car gave a huge backfire and the car bunny hopped while I was driving.. seconds later I pulled over to make sure everything was ok, and there was a ticking/knocking sound coming from the engine bay. Would anybody know what this sound is?It sounds like its coming from the back of the engine, maybe even from behind the turbo. Any suggestions would be helpful. thanks guys Link to comment Share on other sites More sharing options...

And yet again dont go with generic tunes, you need to get it tuned properly. Link to comment Share on other sites More sharing options...

This is a common problem when running generic tunes without checking vitals on the dyno. Sounds like it leaned out. I bent 2 rods on a 10psi generic tune in exactly the same manner after having my car for only 2 weeks. I only had it loaded for about 45mins.On the bright side, you can take the opportunity to beef it up now. The cheapest option for a fairly reliable mid 300 rwkw is an F6 or post 06/06 short from Ford. Link to comment Share on other sites More sharing options...

You should be able to do an F6 short changeover (depending on who you know) for around 6k. If your budget allows, either grab a block and do the build yourself with forged rods and pistons or grab something like an Atomic short. Either way, you should definitely do oil pump gears as well.
