Tuning Experience, SATISFIED CUSTOMER!
by ScoobyTT » Fri Dec 04, 2009 2:00 pm

I was recommended to Edward by a friend of mine during a "car down" time, . I can laugh now but then I was nowhere near humored. I had opted to tune with a guy that clearly did not match up to his claims, nevertheless, Edward got me back up and running. And from there we kept in contact. Soon enough I was interested in original venture, tuning. I have to say, Edward is very knowledgeable, patient and professional. He has been able to share alot with me, and I am far from knowing nothing now as I was before, but still no where near to the teacher. I am very grateful for this information and knowledge, Well since we started tuning, I've never looked back. The car is TOTALLY different. My confidence in Edward has grown and is evident in the performance of my car and the grin on my face in WOT. I would easily recommend any enthusiast looking to tune on any level to Edward. Trust me, you're in great hands.

Excellent Tuning, Great Guy, Priceless advice = Satisfied Customer!

Thank you, but I would have wish you related more of your original problem and the eagerness of new "tuners", not willing to understand, but take people work and try to match it or as their own work. Even last night, I had to correct a problem of a friend where he allow some wanna be tuner to load a rom, making him frightened of the car poor performance.

So Edward sent me a new map last night, I am still grinning. Let me say 1st, the previous ROM worked quite well, so any improvements on this ROM to me (the driver) is very good. Now, the car's response is phenomenal, throttle response is INSTANT, torque is even more noticeable at low RPM. The 1st time I drove on this ROM I felt a little scared

as the car literally felt like it was running away from me. She is very fast and very responsive, above 6000 RPM feels like it still has power. ROM still needs to be tweaked as I found a few rough spots here n there, but negligible and nothing for Edward to sort. The car runs through the RPM band faster, in 3rd I can go from a low 40km to up to 120km in very little time. I need a co-pilot now to log times, or maybe hit the tracks for time trials.
