I just bought my 6 liter and I keep hearing about FICM tuning. I hear innovatives is good for 25-30 horse and greatly improves driveability, improves some on fuel economy and gets rid of inductive heating when running the performance flash. Is it worth the 350 bucks for their FICM tuner? Are cold starts really that bad without the inductive heating when the performance tune is loaded? and how much power am I looking at when I run innovatives extreme race tune(pcm) paired with the performance FICM tune. Im just looking for opinions/past experiences before I pop out 350 bucks for it. Thanks.
