Comparison Of Tuning Boxes

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

1. Drivability
2. Mileage
3. Performance
4. In-gear Acceleration
5. Turbo Lag
6. Dyno Tests
7. Acceleration figures 0-10,20...max
8. Refinement
9. Pollution - Figures
10. Overall Feel

Cars we are using for the comparison are -

1. Punto 90hp
2. Punto 75hp
3. Indica Vista Quadrajet
4. 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.

Great thread. I'm all eyes, to see what comes next!

BTW, Welcome to CW forums! Hope you enjoy it here, just like us!

Well, reading your observations, I feel that the the performance (known variously as driveability, pick-up, less turbo lag) has indeed improved - and it is simply the result of the new box changing the fuelling characteristics. This improvement is accompanied by certain complementary negatives like worsened mileage (which is obvious: better acceleration = richer fuel mix = more fuel burnt for the same throttle position). Pollution figures will remain almost unchanged - the ECU will compensate for this. 

Turbo Lag - Reduced by a good margin

Sankalp - the turbo lag reduction is not because the remapping has affected the turbo. Indeed the turbo works as it normally does, but since the fuelling now has changed towards better performance, the RPM at which the turbo kicks in is achieved faster giving an impression of reduced turbo lag (lag is the time taken for turbo to spool up, right?)

That is right but technically, the turbo spools up only when it used to do before. I have petes in my swift and turbo lag is not actually reduced. Accelaration is increased and hence we do not feel the power drop.

That is another way of saying it...

Turbo is nothing but a turbine cum compressor. it rotates when the exhaust gases pass through it. if you find a change in the performence of turbo, it just nothing but increased gases passing out. or this box is sending more fuel and in turn more gases are coming out of the exhaust making turbo to start early. It is also very clear from the statement that mileage dropped by this box. 

i did not use it but from the posts it looks like people are being fooled by this box. it is nothing but increase the fuel supply to engine. and give you more power. 

if we get access to the engine control box (MCU) mostly this can be done by changing values in the original system without spending this 28000/-. Request some expert to comment on it

@ ProBiker, even I was interested in similar kind a thing and came across Drake Tuning Box 2. It would cost around Rs.7500/- and I'll be ordering it via eBay from Italy.

Do you think that's worth it? And what's the cost of the tuning box, you're talking about?
