I thought it was a no brainer as well until this afternoon when I spoke to him. As Rednose mentioned, he is considered one of the best in the business and has stated that I can try both and see which I prefer which is why I brought the question up.
Guys, I was just wondering which would you go for and why ? I was speaking with my Tailshaft builder today and he mentioned that he would go with a 1 piece as it would be lighter and improve throttle response. He also said that it wouldn't vibrate like some people think it would.
Mine was running 18psi with a similar tune the OPs. In that time I've only run Toyo R1Rs and Nitto NT05s and I've had 0 mechanical issues apart from a faulty BOV.
Grandfather drove Fords, Father drove Fords, I drive Fords although must be said that I probably would've owned something turboed if I didn't have my G6ET. I would've had a Ford daily anyways :sungum:
Same thing happened to me when I was looking at a XR6T at Dale Ford here in Sydney. Wouldn't let me even test drive it. Compare that to the service I received when I bought my car from Audi centre in Sydney. Treat their customers, young or old, exactly the same. I loved rocking up to Dale Ford a couple weeks later and now they've closed down LOL.
You mention that if BPR fit the box, you will lose warranty. Do BPR warrant their work ? Because if they do, you can be sure they won't for yours if you let Nizpro tune it.
