I read most of my magazines front to back pretty throughly and I found a small add in the Roundel and European Car magazines for a guy in CA who bores out your exsisting TB for $200 including the shipping. He says the total turn around time is 3 days. 1 to him, 1 for work, 1 back to you.
I dont have any magazines here at the house, so I dont have a the number, but its in a few different mags.
From what I was told this guy does work for Dinan as well as BMP. He disassembles the TB totally bores it to its maximum, replaces the butterfly with a properly sized new one, and adjusts several other parts.
The only downside is no car for 3 days, but I can deal with it.
Once my end of year bonus hits, its gonna happen, I'll let ya know how it works out.
john, it might be cheaper than the DINAN, but with that u get the upgrade to stage 3 software for free. no software comes with the bored out TB, and to upgrade to DINAN stage three otherwise would be expencive, no?
