I was interested in taking a Tuning box for my Punto 90hp. I found 5 different tuning chips, a couple of remapping companies. However I was not sure which 1 to take, how are the gains, what is the effect on Mileage, Long term effects on engine, etc. So too many questions. Then tried to google for answers. However I found very little info on the same. I did not find any Dyno charts for any of the products. So I contacted all these people & told them that I wanted to test them thoroughly. I told them that we'll be testing them & comparing. The comparison is to check the Drivability Mileage Performance In-gear Acceleration Turbo Lag Dyno Tests Acceleration figures 0-10,20...max Refinement Pollution - Figures Overall Feel Cars we are using for the comparison are - Punto 90hp Punto 75hp Indica Vista Quadrajet Linea Multijet 90/ Indigo Manza Quadrajet 90 Already I received a couple of boxes. Testing started on some of the parameters. Yet to receive the remaining boxes so that the V-box & dyno tests can be started. Some of the big players are actually not Comfortable in the complete test - reasons are obvious. Yet we'll try to source them from other means for this comparison. This article after completion will be the most exhaustive & comprehensive testing on Tuning boxes available currently in India.
