it seems the people who most doubt remaps, etc, are those who haven't actually had one, or have had one but on cars which don't respond well to them.
turbo diesels respond best to a remap, followed by a turbo petrol. remapping a non-turbo petrol, or a diesel, will see hardly any improvement whatsoever in performance, although deadzones can be mapped out which is handy if your car is like a cayman s which has a deadspot at about 1900 rpm.
my car is quicker than my mates corsa 1.7cdti which has 130 bhp so..not massively but enough for me to have to back off a fair amountt so i stand by a true 149bhp as per the dyno print out. not doubting some tuners to screw things up but if you stuck at the reputable ones, for example i use r-tech where possible, or AMD technik or custom code...if you use bob in his back yard then perhaps not...
yeah that's pretty much why. though i reckon the remap took 2-3 seconds off my 0-60. apparently it's 10.2 or something from the factory, i got 7.8 to 60 after the map!
considering it's more economical now as well..it's actually paid for itself by now..
Anyway i fitted some news lights a couple of weeks ago (can't remember if I posted on here but anyway) after weeks of debating getting a HID kit..i finally caved in.
i couldn't put a HID kit in my standard reflector headlights because the scatter would have been appalling. so i bought some hella celis lights and ran around with some phillips ultra blue xenon bulbs for a while, which were actually really good. they are halogen bulbs but burn at about 4000k, best halogen bulbs i've tried which are road legal.
anyway i stuck a 4300k HID kit in my car and very happy with the output and beam pattern. i chose 4300k because i wanted maximum light output and an oem look. anyone who has 6000k hid lights is a chav.

i even got the install very tidy with holes in the lense caps with seal in place, ballasts mounted on the lights out of the way (going to re-do them as i found out there's space underneath the lights for them), cables nice and tidy.
