I know that a lot of you have been waiting for this review ,but i wanted to perform comprehensive testing on this product of juice box before i can give an objective review ,i have also been busy with many other things (having 3 jobs).
So here is my review in short:
* Installation was HARD for an amateur like myself ,however ,it wasn't impossible ,it took me over 1 hour and half ,but everything was perfectly fixed ,i have NEVER EVER taken a screw out of my cars , imagine how did i feel when i was opening the ECU :p
*Terry ,the owner of Jb products,was VERY helpful and supportive ,NO ONE can beat terry in customer support and follow up ,sent him many logs and got the right map for my car.
*the car is SIGNIFICANTLY more POWERFUL ,according to terry ,i am getting 80-100 RWHP ,still need to dyno though.
*I am getting 14.5 PSI under map 2 ,with gasoline 98 RON (supper) ,i had to start gradually with map 1 then send some logs to teryy ,i also had to wait and do some WOTs till the car adapts to the new configuration.
* installed DCIs from JB ,this gave me additional 10 HP aprox ,the greatest advantage was the SUPERB throttle response i am getting now ,the car seems to have LONGER BREATH ,i believe this upgrade should be in EVERY E92-E93 engine.
*my over all impression on JB4 and DCI : VERY satisfied.
To ALL those who think they are tunning NERDS and that the tuning world is nu clear physics that no one BUT THEM can master ,i tell them : i did everything on MY OWN , WITHOUT you!
To ALL beginners ,do NOT hesitate ,you can install / uninstall / upgrade...anything in your car on your own....need some help....call me!
