@Ganges I do not agree with the above said a remapped version will more or less shut the waste gate in order to boost the pressure. If you are wasting your trump card then how come the conditions are same. Moreover the remapped version will be tuning the pump and rail pressure in tune of 2200 or say 2400 where as in case of stock it would be 1800psi now you can guage in which condition the engine is strained. --- Double Post Merged, Jul 24, 2015 --- I bought a hatch back after 1 year of research and you know discussed in details about VGT and FGT and other engine transmission brake releated issues with all the companies tech rep available at the dealers none of them could satisfy.With Fiat rep I had 3 to 4 discussions each lasting more than 2 hours without even a single TD.Then I took a TD that too only of a 75 hp and that too linea and bought a Punto. I could get if Linea can handle it then Punto surely can.
