@Vijay, The Intercoolers were fitted perfectly i personally checked myself. Well the situation became more wrose, Till i was there with those TASS Guys on saturday, the LINK ROD was faulty and hence they changed the rod and gave a try, still the situation persists but with less noise this time. The last news i got from them today was the Stud is the only thing that needs to be checked now since the issue persist, as to others were dismandled and fixed again. I too Hope the stud could be the issue. From no where this issue creeped! @Bhai, I met one more Punto MJD on satuday and he says his punto is like a rocket and has not felt any heaviness issue till now. Seems something between the wheel and the engine is creating the problem, Cos my car had been taken to the engine room and did a thorough test of the engine and the results were as expected. TASS Guys feel the ECU is doing some malfunctioing somewhere, but they are also not sure. Once FIAT gives a go signal they would change the ECU in mine and check if the issue perist but those testing will be done only after my confirmation.
