After a long hiatus from the GN community, I’m just starting to build two project cars (86 & 87) that I purchased recently. The primary reason for this thread is to determine whether purchasing an aftermarket system like DFI, XFI or BS3 falls into the category of nice to have or need to have.
Since I also have an 07 Corvette which I tweak with an HP Tuner (someone else did the primary tune for me), it’s easy to get a little spoiled with the number of different values you can control when compared to a stock GN ECM. At the same time however, having that kind of control over an engine can get pretty overwhelming at times as the learning curve is pretty steep. While I know from tuning the Corvette that it’s nice to have control over so many different aspects of the car, I also know that at the same time my motor *should* have the capability to go almost (if not just) as fast with just a decent carburetor. I also know this is true with the GN as many people have cars that are insanely fast while still running only the stock ECM and a custom chip.
I have different goals for each of the two GNs as one will be a daily driver and the other will be used primarily at the track. The common goal between the two cars however is that regardless of the type of turbo I run or injector size or any other performance upgrade that I have, I’d like to know that I’m always getting as much performance out of the car as is possible.
In case anyone has noticed that this thread is also in the Performance ECM section, that was actually done on purpose. What I was hoping for was to hear from people who are very familiar with these systems as well as people who had considered one but decided against it, or even had one but later decided it wasn’t worth the extra money (and that they should have invested in something else like a bigger turbo as an example) and subsequently would have little to no reason to frequent the ECM forum.
So what’s the verdict? Nice to have? Need to have? Or somewhere in the middle?
Thanks for reading,
