I've also had some recent dealings with PDT Dave over the last couple of months and can only echo the positive comments made by the original post.
If anything he is almost too helpful in terms of spending time on the phone and his first hand knowledge of what is possible with my car (an Ed30) has made me spend some cash under the bonnet..with plans being hatched for further upgrades.
*Twintercooler GB anyone??*
I'm not just on the "slippery slope" now - I'm on a Skeleton-Bob thundering head first down said modding slope.
Even at my current mild level of tuning, Stage 1 Revo, Autotech pump, Dbilas intake and Milltek DP & Cat, the car is tremendous to drive.
The intake and downpipe were only fitted there today (cheers Dave & Danny) and I really like this component combo already.
BTW Having heard Dave's mobile ring about 40 times today, just in the time I was there, i think I'll get him by email from now on. Cause that guy is busy..
As they say on that well known auction site, "would recommend and would use again".
