Short chat with Mark at AutoMark today and car booked in for its final mapping session on March 12th. Hopefully all goes to plan on getting the boost reliable at 26psi. Been 4 years since the last visit when engine had only done 3k miles so hoping with some tweaking it might get over 430bhp
A similar spec engine in a Ur with this turbo is producing 470bhp so shouldn't be too hard....
