Wow matey and you are driving like crazy without the tweak of these fitted parts.
I would recommend drive off the boost until remap/tweak,you can cause more problems than normal.
Contact in your interest(for safety reasons and performance too) soonest as possible Duncan if he does your first map.

It's the maths! Pie r squared.
2.5 = 19.6 sq inch
3.0 = 28.3 sq inch
So you have in effect halfed back pressure, by increasing the area by nearly 50%.
See 1/2 inch does make a difference - at least that's what I've been told.

The system is a one piece made by Alan Jeffrey for big fud wr1. I bought it off him last wk it's a awesome exhaust and sounds lovely and at the same time not to loud... Yeah Duncan appreciate your help when u can mate really want to sort!!!!!
Any other advice would be lovely
Harvey I'm saving for your headers and up pipe and the fuel to get to u as I live in Mansfield
Cheers again chaps

You got me thinking now. According to the laws of physics less back pressure on a turbo should increase efficiency. Therefore spool should be faster for the same mass of exhaust gases. Sounds like cylinder head/manifold velocities are slower so you have made it more cammy off boost. Or am I getting this completely wrong?
