My Dear Ravanger,
Failure leads to innovation, i am sure you are true to what you are saying, but sharing knowledge is vital to all of us, cause we are all still learning.
People like @noman8ff, @akifjanjua, @SuhaibKiani, @joinami, @hsumbal1@, @kambrit, @veitnam are like Gurus when it comes to 4x4, they are like encylopedia to this game. I would honestly suggest that before you badmouth these people, think who you are addressing to. They have been building 4x4 since you and I thought that 4x4 were 2 numericals and an alphabet. Engines, Transmissions, frames, bodies, modifications, you name it & they have done it over and over and over again.
So you should know when and who you are bending your relations with.
My 2 cents.
To make it easy for all members and remove the bar to secrecy; i am assuming that you are getting your work done from Ali Asghar in F11 (who used to work for NUIC and now doing things for you as he has managed to set up a place for himself). He is guaranteeing 7-8km/l with modifications and he believes you may get upto 11-12 average on a 2f with stock configuration.
