firstly hey, im James new to the site
Im having to trade my Lexus IS220d in due to running costs, insurance has shot up £400, and MPG isnt what i thought it was,
after extensive talks with listers lexus in Cov we appear to have found a 1.9cdti SRI  that not only lowers my monthly premiums, but is £600 cheaper on insurance and 10mpg better than the lex so saving me around £200 a month ish,............seems a no brainer to me
ive used the search facility on here extensively and found most of what i was looking for, but can you guys clear a few things up for me please?
1 - Remaps - i get the general torque/power gains but what i cant find is the average MPG thereafter?.....driving normal, booting it ect
2 - XP Pack - I can get this for £170, how much on average would fitting/painting be?
3 - lowering springs - i like the look of the eibach 35mm drop - how much would fitting be?
4 - HID kit - again average fitting costs? (im not good with self-fitting things, i struggle with ikea furniture!!)
Many thanks in advance, if ive missed any of the above info in my searches i duly apologise
