  1. Please just need some help with low rpm hesitation

    Yep Do you have a Bullitt ?. And is it US or Euro model ??
  2. Please just need some help with low rpm hesitation

    If it’s the same issue I had you’ll notice both in stock and tuned. slight surging when pressing the throttle and doesn’t feel smooth
  3. Active exhaust actuator option?

    The image actuator will not fit your car. The image shows a 3 pin connector and yours will be 4 pin unless it’s a gt350. the bmw M3 actuators are the same as ours.
  4. How would you rate the Borla S-type Catback on the loud scale?

    Yeh Stype with the H pipe is defo the way to go on these. Maybe a slight power loss but nothing you will feel. after broken in the Stype will have sort of chambered sound at low rpm’s. both the H pipe and the super 10 flow master will remove that trumpet and rasp.
  5. So what's the deal with the 2K-rpm rattle?

    So what’s the rattle that I’m hearing then?. mine happens in neutral or driving at exactly around 2-2.500 rpm and you can either accelerate through the noise or let off the gas. also happens during cold start only. Makes this rattle noise for about 30 seconds and then suddenly stops as the revs...
  6. Exhaust Tone just sounds off, any ideas?

    Been trying to contact the OG I solved this issue….. 1. Tune ONLY get a tune from Steeda. They already have all the maps for our euro cars and getting a US tune will cause you some problems. 2. someone else mentioned the Active exhaust and yes that was the problem. We both have euro Bullitts...
  7. Active Exhaust issues

    Remember if you delete the active exhaust just pulling the fuse and leaving the engine light on isn’t good enough. the ecu will command that their is either a blockage or An exhaust flow problem and it will change the AF to compensate. they need to be deleted properly
  8. Active Exhaust issues

    So I’ve been complaining for a while now that my car intermittently sounds like crap and the exhaust will sometimes sound crisp and other times strange but still loud. decided to pull the fuse on the active exhaust while in normal mode and the exhaust seems great. I don’t have any issues with...
  9. What's the deal with ghost cam tunes?

    You’ll get tired of it quickly particularly in traffic. It really screws up the driveability of the car at lower rpm driving. Don’t think it will mess anything up but your fuel consumption will drop dramatically and I don’t know if the unspent fuel will eventually kill the cats.
  10. So what's the deal with the 2K-rpm rattle?

    Are we all talking about the same 2k rattle ?, because there is a couple of them. the most famous is a loud rapid clicking noise almost like injector clicking when slow applying the gas. many thought it was the vct phasers but it looks like it’s the HPFP pump. They all make noise but some...
  11. Premium Fuel Tune - Long term fuel trims

    Thanks for your help. Looks like I was trying to solve a problem that I never had.
  12. Premium Fuel Tune - Long term fuel trims

    Yeh At idle lambda is 1.00 and Stfts 1.00. Using the sctx4 and these should be perfect. I have to admit I did a Kam reset and the LTFTs plummeted. I’m guessing they may need time to come back up with a few drive cycles. maybe the ecu doesn’t trust the O2 signals until the rediness is totally...
  13. Premium Fuel Tune - Long term fuel trims

    Hi All Quick question if I have a premium fuel tune and I add fuel which may either be slightly contaminated or less octane. Will this affect my Long term Fuel trims into negative 12%?. also it’s 36 degrees centigrade here at the moment and the IAT temps are through the roof. I asked because...
  14. So what's the deal with the 2K-rpm rattle?

    I think the sound this person is hearing is probably the low rpm buzzing or rapid clicking noise when either in idle or when tapping on the gas at low rpm. I originally thought this was the vct solenoids as many did at the time. I believe it is the HPFP when it transitions between low port...
  15. So what's the deal with the 2K-rpm rattle?

    I honestly don’t hear anything out of the ordinary.
  16. How would you rate the Borla S-type Catback on the loud scale?

    Not with an H pipe it won’t. the flowmaster mid mounted takes away any rasp as well and keeps it loud
  17. How would you rate the Borla S-type Catback on the loud scale?

    I also thought the S type was a little loud. The best thing is to remove the x pipe and put an H pipe. I also later added a flow master super 10 right after the headers before the H pipe. Sounds great
  18. Vct solenoid rattle 2020 mustang

    Hi I don’t think I have the 2k rattle but is it normal to hear what I think are vct solenoids rattling a low rpms. Normally it’s when accelerating at low rpm from about 2-2.5k rpm. it’s not the 2k rattle because that sounds different. Just wondered if anyone has this ??
  19. Going back to Bullitt after 2 years

    Yeh no so easy I’m afraid But the cars already here are climbing in value every day
