Anyone regret making the switch to EFI?

Sorry if this has been discussed , but has anyone made the switch to EFI and regretted it? It is next on my radar as far as things to do. I really like the concept if it obviously but worry about glitches and reliability. Have not considered which brand I would get, would probably mean towards Holley. I appreciate and real world experience you could share..thanks.

Re: Anyone regret making the switch to EFI?

Nope. I may regret, or more accurately wish I had a different system, but I do not regret going EFI.

Need to make an AFR adjustment? No more draining fuel out the carb, changing jets, checking spark plugs in hopes you're close. If not, redo. Now I take 10 seconds and go through the handheld and done. Plus, it auto adjusts for changing weather.

Need to change timing? No more reaching in a hot engine bay, reving the engine to check timing with your light. Not to mention the hassle of changing a timing curve. Now I just go in the handheld, and adjust the timing at say cruise RPM, and maybe add a degree in the mid range. Or maybe I am idling for an extended period of time, well I can bump up the timing since idle timing isnt restricted to base timing.

A learning curve, and expensive, but it's the way to go IMO.

Not one bit, easily the best decision I’ve made for my car. Holley sniper is pretty good, it’s great with timing control. Easy adjustments and fine tuning is all done on a laptop sitting on the couch.

This is good to hear. So far the best thing I did was the TKO600 from Silver Sport,made it seem like a different car. EFI seems like the next logical step.

Hey Pat. It was nice to meet you at the car show yesterday. Your car is awesome. Let me know how the EFI works out for you if you take that leap. Saw ur link IRT American Racing Headers...mine hit that f***ing speed bump on the way out. Again, good meeting you and good luck.

Nice meeting you too Harry!. Thank you for the compliment on the car. Certainly leaning towards EFI. That speed bump would have got me with my hookers. American Racing Headers cleared it with no problem. Hope to see you at more shows.

Re: Anyone regret making the switch to EFI?

With the cost of carbs lately there isn't a large difference in cost between EFI and a carb. I personally like the EFI over a carb. I even old enough to tune and jet a carb. The EFI is just a cleaner install. The throttle response if tuned correctly is far superior to a carb.
Just my $.02 but I find the fitech is almost fool proof. Holley is much more detailed. Any service or trouble shooting I found you have to go back to Holley. There answer in my case was send the ECM back to us for testing. Amazingly it needed a new computer. Then the download didn't work from the CD. I then had to call Holley and luckily I came into contact with someone who really knew how set the basics up. 1.5 hrs later on the phone with holley the vehicle fired up.

Re: Anyone regret making the switch to EFI?

I was an early user of EFI with the first Holley ProJection systems. It had to be the late 1980's. As simple as the system was, it performed better than any carb I ever had on the car.

My last carbed vehicle was a 1973 Impala I junked when I bought a 1989 GMC S15 Jimmy.

Surely.....you can't be serious?

EFI is vastly superior in nearly every way....but the dollar cost and time cost difference is significant. Don't kid yourself.

What did you come from before the tko? I'm hoping the t56 does the same to my car!

Muncie M20. The car is now just a treat to go down the highway with. Before I dreaded the highway. I have 3.73's and the setup is perfect now. Lower first gear to give it more bottom end and that wonderful OD 5th gear

A basic self contained throttle body system good for 400 HP can be had from Fitech for $800.00.

Moving up a bit, these systems start at about a grand.

Then upgrading to a decent fuel system that works* can add a bunch more.

*works meaning some sort of system that prevents fuel starvation during cornering, braking and accelerating, such as a Stealth tank from Aeromotive.

If I do it Paul, I will want to do it right. I will lean on folks like you to guide me to where I need to be. I would rather spend the money once and have it right.

Re: Anyone regret making the switch to EFI?

I don't regret it, but it is a fair investment and the fuel system is most of the work. Yes, it does run "better" than the out of the box, 30,000 mile AFB I had. Starts easier, uses a very small but noticeable amount less fuel, smells less. I did it on the cheap, and I think my total was $1150 for tank/lines/FiTech… And is it $1150 better, no, definitely not. Not to me. BUT to my wife (smells less). And to a noob at classic cars that have no clue about automatic chokes, or carbs that evaporate empty over weeks with the crank/pump, and how to not flood a car. It might make a car pleasant that is almost undrivable to them. I am also planning on controlled spark, and that is a lot of the reason I went with it as well, and that will not cost me any more.
Plus I am going to experiment with E85 which is dirt simple now, just type in a 430 CI instead of a 350, and try it out.
Also adding in A/C it will automatically bring the idle back up similar to a modern car when the compressor engages.
IF I bothered to tune the carb we had, and IF nobody buy me ever got near it, I probably would have regretted it just on the expense. I don't have any complaints, not one, about overall performance/drivability/or other issues. But I always would appreciate having that $1150 in my wallet again. I would assume most guys would not cheap out like I did, and would be closer to $1,800 or so.

I have 1 car with a Holley Dominator EFI, another with Holley Super Sniper efi, and a complete Holley HP that is going on a 3rd car.

Zero regrets.
