    RENNTech HHT

    Purchased on their Black Friday Sale, the Hand-Held Tuner arrived earlier this week.

    Installed today in my wagon, took just a few minutes. Went for about an hour test drive around the city just to be sure it didn't cause any faults. Seat 'o the pants meter noted a crisp throttle and quick upshifts as well as holding lower gears longer. Slight turbo-lag still present in normal driving but I didn't stuff the pedal either.

    Heading out on the highway for a few days skiing tomorrow. The 5 hr drive should provide better opportunities to appreciate the tune. My local dyno guy is away for another week so I'll update once we've done a few before and after pulls. The beauty of this HHT is that it takes only a few minutes to switch between normal and tuned.

    LOL, I have a good imagination Click here to enlarge. After the highway drive I should have a better impression, so will report back. Of course the real answers will be on the dyno.

    It's winter up here so, although I could book a dyno appointment next week, don't think its advisable until Spring. To get the most out of a dyno session, the car will need the summer high-speed tires mounted, a fresh oil change, and a boost-leak test first from what I've read.

    On my recent highway drive, when I stuffed the throttle for an on-ramp merge, the entire drivetrain gave a shudder when the boost kicked in, then it was off like a scalded cat! That was a first Click here to enlarge
