I have an FG with cat and dump already done and tuned. I've recently had the standard Catback replaced with an xforce 3.5 system. I have a lot more bottom/mid power now. Do I need to get it retuned? I'm assuming the car building boost better now. Will the car/Ecu do any necessary adjustments to avoid leaning out? Is that even possible with this single change? Thanks.

the rego thing may just be an invoice error. the same owner is on both invoices, 1 yr apart. no pics taken yet. but for reference, it is just a bone stock fg lightning silver xr6t. 18" wheels. no other external accessories, or identifiers.

Hi, I've just bought a used 2010, silver, xr6t manual from an Adelaide dealer. the car came from vic, but without the old books. all I have are the two most recent service receipts/reports. it's done 70000kms, standard, previous regos of zms212 and xub539. looks in very good nick throughout(underbody, engine bay, interior). mechanically it seems excellent and no signs of the usual drivetrain clunks and noises. it's from narre warren/ knox area. I do have the old owners name/address, but I'd rather not directly contact him, out of courtesy. if anyone has any info about it, thankyou in advance. cheers.

I've just bought a used, stock 2010 xr6t manual. in my first 350kms, I'm averaging 10l/100km, avg speed of 55kph. there hasn't been any true gridlock city traffic, but about 100km of regular suburban driving (avg speed around 35kph) in this mix. running bp98. as the car is new to me, ive been giving it several small squirts through 1st and 2nd gears off the lights/at intersections. I'm really pleased with the fuel use. at 110kph(actual) it sits on about 7.7-9.2l/100kph (wind direction) and at 90kph, it's been around 6.7-7.2l/100kph.
