Hello!
I'm Gakis Stavrianos, road test editor for Power Techniques Magazine Greece. We are the best & more popular tuning magazine in Greece. Our site is powermag.gr
We have a Fiat Grande Punto T Jet for a long term test and we desided to tune it a little bit.
Our setup:
KW Variant 2 suspension
Full inox custom exhaust with downpipe and cat back
Re mapped ecu from a tuner here in Greece, named Dynodrome.
We own a rolling road dyno, Dynomet 4X4.
We saw about 138Ps as standard. We made some dynos with some other Punto T Jets an all of them was about 136-139Ps an 24kgm of torque.
The inox custom exhaust has 57mm diameter an the engine after the exhaust didnt gain nothing! About 2Ps actually.
Then we had 2 days on the dyno trying to remap the ecu. Finally the turbo is boosting 1.3 bar overboost, stays for a while at 1 bar and it goes slowlly at 0,6bar at 7.000rpm.
We saw about 144Ps and 25,5kgm of torque.
When we removed the air filter and we left the turbo only with its hose we saw about 146,7Ps.
I have all the diagrams in .jpg and a will upload them.
The clue? The t jet engine has very good exhaust system.
Thats for now....
