Hmmm, it's so hard to tell what is really going on with these dynos.
I only ever went to Dyno Dynamics because even back then (mid 2000's) it was agreed that their @ wheels figures were the only generally comparable or trustworthy ways to get an idea of before/after power gains and torque gains.
Did you run a dyno before remapping on this dyno to get an idea of accuracy?
Not to say I don't believe the peak power. I know a few owners who've had 160bhp dyno figures with relatively lower looking torque figures and that is usually due to a k03 turbo... However 160bhp at 4000rpm seems VERY high for a GT15 turbo.
If that is correct I'd be very cautious of high EGT causing turbo damage if driven at sustained high rpm and high load. Given the power plateau width and short gearing in the HDi90 I can't see the point of having power so high up the rpm range. It's no faster except in 5th gear (110mph+ hehe), and when used in that condition EGT management is going to be a huge consideration.
I'm excited to see how this car goes when driven hard using that higher rpm power band for sustained periods... in summer
What hardware and software is your ECU?
Is it a 162?
