Hello all,

I have a 2005 Continental GT and was reading about ECU tuning upgrades. I see that there is one out there from GIAC, that supposedly gives 100HP gain. Some state that there was transmission shifting issues after the upgrade, and that the car needs a TCU upgrade after the ECU ugprade to correct issues. Did anyone perform any ECU upgrades, and if so, what do you recommend? I was hoping to learn from others who have done some tuning to their ECU's. BTW, I live in the Chicago area.

Thanks a bunch...

 

I have a 2007 GTC and had the ECU done by Justin at Rennsport-one . I have not had any problems with my Trans at all . I got 100hp and 120 LB T . Justin also give's a 45 days for you to try it and if you don't like it he gives all you money back . I bet you will love it I do.

 

Fabspeed had the opportunity to do an install on this stunning GT-->

Power is up 100WHP and the torque.....well let's just say...CLICK HERE
The car was supposed to be featured in ML&E and will now be featured in this summer's edition of Luxury Auto Direct. We installed our 3.0" exhaust system which includes the downpipes and secondary catbypass H-Pipe with PES custom ECU upgrade.

How much is the ECU upgrade to get an extra 100HP? That is a ton! Why would you not do that lol

 

$3,695 for the ECU Upgrade.
