Got to Thorney in Milton Keynes early about 8:40 so I had a look round and took a few photos in the car park
Handed over keys at 9. I had the car lower 30mm all round on Eibach Prokit with wheel alignment included. Replaced pre-cat with Milltek downpipe, and had a Milltek resonated cat-back. Then it got Thorney custon remap. Also had my 2nd full service there before they fitted the parts.
Here is the car being set up on the rolling road
Power at flywheel 205.6bhp up from 182bhp.
171.6bhp on the road up from 152bhp
Was told if I had a full sports exhaust system I would have 15bhp more, but they don't make one for the Astra 1.6 turbo. The Milltek downpipe used is the same as they put on a Corsa or Meriva VXR as the engine dimensions are the same. They used the Milltek cat back for a 2.0 SRi. The only option is to wait, or see if there is anyone who makes a custom sports cat to fit but that would be too expensive.
I thought I would have got 210-215bhp but car still feels a lot different. Power delivery feels smoother and the car pulls a bit stronger through the mid and higher revs. Where, previously, the turbo run out of puff after the mid range, I can feel the torque stays up right the way through the revs to 5000rpm. With the sport button on it's feels almost twice as quick as before.
Suspension is a lot tighter round corners now, without feeling much harsher over normal ground.
While I was there, they Tech2ed my steering wheel controls and trip compute,r which hadn't been programed since I retro fitted a CD70 Navi, for free.
Here is photo later showing car is lowered.
