Innovative tuned FICM installed

Like the title says. I received my spare FICM back from Innovatve last week and tonight I finally got around to putting it in the truck. I got the mild tune. I don't have a lot to report yet, but I can tell you after taking it out for a 10 minute ride around town there is a DEFINATE increase in throttle response in my truck! The damn throttle snaps like a stock car now!!! Not that it was terrible before, but it was a noticable increase. I didn't get on it hard when I ran it tonight, but my guess is there won't be a huge difference in SOTP power. It's hard to explain without taking somebody for a ride, but it just FEELS better... I've been told there might be a small fuel mileage gain as well, I'm planning on checking that out over the next few weeks . It might be hard to judge due to the winter fuel around here, but once the weather warms up I should know for sure. I'd like to put it on the dyno just to see if there is actually a RWHP difference before installing my new turbo as well, but I don't know how practical that would be unless I changed back to my stock FICM between runs to measure the difference. All in all so far I'm happy. I think its a nice upgrade for people to consider who already have all the basics, and are wondering what to do next.

Yes, you can run it with or without a tuner.

Yes you can, but you should get yourself a set of injectors first.

Why would he need a set of injectors before tuning the FICM? Or is there more to this story than I know?

You will get more of a benefit to the ficm tuning. Im not 100% certain, but i beleive ficm tuning just opens up the pulse width more than what flashing the pcm can acheive, so bigger injector + even more pulse width equals more noticible improvement. But it works fine either way, but if you do ficm tuning first then do injectors you need to send the ficm back in to get reprogrammed....

You are both correct and wrong at the same time. Yes, bigger injectors will see more benefit with FICM tuning, but no you don't need to re-burn the FICM once its done if you add larger injectors.. The FICM and ECM work together, but at the same time they are separate systems. I'll get Eric's take on this to make sure I'm not giving false info, but I'm pretty sure I'm correct.
