    Hi All, Had my 3.0SDV6 tuned yesterday - ECU rewrite. Standard power/torque 215kw/600nm. Now 240kw/680nm. Pulls even better than a steam train now :) Couple of issues (or 3): Cruise control, ASL (speed limiter) and the Auto Stop/Start no longer work :( The cruise control light/icon/title...

    Hi Everyone. 2001 2.5 DHSE I was looking over the car today and found a small black box behind the EAS box. On it is a sticker saying 'power Link' and a number 'CL4'. It has a rubber pipe connection which is either vacuum or pressure ( couldn't see where it went) and one black cable...

    Wondering if anyone knows the 0-60 times for the V6SC tune + pulley performed by ECU tuning group in Fremont, CA. Maybe someone could comment on the performance before and after the tune. The tune brings up the HP to 440 and torque to 400. Thank you.

    Hi Guys, my 1998 P38 2.5 diesel has one of these fitted on top of the battery (sorry it is out of focus): It was fitted when I bought the car and not sure if it is boosting performance or not or increasing MPG and it claims to do both. I have no instructions and I can find nothing on the...

    Anybody out there with any experience of chip tuning the SDV6? Stock it has 225kw/700nm. Been quoted 261kw/800nm "with strong torque gains at all engine speeds. Economy improvement by nearly 10%". Just using chip tuning. I know standard numbers are big enough but just asking the question. I...

    Seems the biggest fear among a lot of us is the long term reliability and fear of higher wear and tear on engine (or god forbid a blown motor:crybaby2:) . Would love to hear from some owners with higher mileages on their tuned V8 Supercharged models with tunes from ECU Tuning Group. I've heard...

    Hi. I was wondering what my options are for tuning an HSE V8 for more power? I've read about ECU tuning, but wouldn't that void the warranty? And what about fuel economy?

    Anyone taken the plunge and reflashed their dog HSE? This company is suggesting they can add 26hp and 30NM of TQ with a reflash from the UK. I am wondering if anyone in the US has ever tried this on their AJ. Now that I have big tires, i need all the performance/efficiency I can get...

  14. Range Rover Mark IV / L405
    With only 300 miles on my new 15 SuperCharged, I decided it was time to start messing with stuff. Me, a couple guys with sub standard tools, a dremel, blow torch, sandpaper, and a dog decided to pop the "bonnet" and upgrade the pulley. ECU Tuning Groups video for the procedure is 3 minutes long...
