hi,
Had it done last year, I really could tell difference at time but now 'used' to it.
Still does shove you into seats when you floor it even at 70 on motorway.
My friend, on who's farm I shoot had his 3.0 done there and it leaves me for dead on acceleration at all speeds. But he has to be gentle in snow and on ice even with AT tyres. If you can afford it its worth it. David.
