Hi mrjheeta,
I would not personally recommend these sort of companies, they may be cheap but its for a reason.
These companies will generally remap any make and model and are usually out of the box maps.
This brings a few problems forward.
1. irritating things like flat spots, rubbish cold starting, fast idle, etc.
2. unacceptable power gains compared to other remaps
3. don't take into account any mods you may of made.
Yes I know that companies like Revo, Giac, and most others are only out the box / off the shelf remaps, they still can offer you different maps for different mods, different engine codes and systems, (i belive there are about 15 different types for the 20vt KO3)
The best in my oppinion is Custom Code. They are all I will ever use.
They are the best because they start with a rough map to suit your car like any other company, but then they live map / real time map it on a rolling road to get the best power and drivability.
Me and my mates all run CC.
