Anyone running fitech ultimate ls?

Manifold is the same Chinese knock off of a Precision Manifold that everyone is selling now including Holley. Although I have not run that particular FItech unit, I have not been happy with the carb style units we have used. At first they seem great, but after awhile, we have had to fiddle with a couple of them and had to reload the software on 2 of others to fix some issues. As far as the intake, I have run 2 of those Chinese intakes before and also pulled them not only because of power losses, but they tend to "hammer" or "echo" and sounds like somethings broke because of the thin sheetmetal. They really don't work properly on small cube motors.

We installed a Holley Sniper on a ZZ502 in a Chevelle last year right before GG DFW. With zero tuning or test miles I drove it 400 miles roundtrip with zero issues. Car now has almost 3000 miles on it, and I have not touched it since I installed it. Oh, and this same customer also has one of FItech units we had trouble with on his 55 Sedan and has considered swaping it out to a Sniper.

I put a FiTech on my '68 Camaro. It was the #30002 600 HP unit. ( I believe that is the right number). I put mine on when the weather was in the teens and 20's. Had a little problem with the idling, but after a call to FiTech they helped me with some settings. I've now got about 600 miles on it and the more I drive it the better it seems to run. Most definitely one of the best purchases so far for my car.

As a follow up to my above post, I now have about 500 miles on mine and so far I would say I'm satisfied. Part of me wishes I would have spent the extra $500 on a Holley HP setup, but the FiTech is doing everything that it should for the most part and I knew going in I wasn't getting a Holley level product. Some additional thoughts now that I have been driving it.
Keep in mind, this is a stock everything 2002 5.3 with 190k miles on it and a TH350. None of the motor internals have been changed, just accessories and the FiTech intake.

Motor fired right up and idled great. Throttle response was ok intially but is getting better. Working through a hanging idle.

The IAC makes a TON of noise. It is literally all you can hear at certain points. Certainly my biggest complaint with the system.

I was having a stalling issue when coming to a stop that got worse as I improved the hanging idle, and now seems to be fixed after some additional tuning. The tuning parameters aren't very well defined so it took a bit of googling to make sense of what affects what in the settings. There is a decent amount of help out there though and it continues to get better.

There is no connection to factory oil pressure sensor. Another simple addition that should have been included in my mind.

The motor fires as soon as the key is turned whether its dead cold or 200+ degrees.

The issue I see is with the shorter runner it kills low end torque.

Don't know but is it only for cable driven TB?

Yes, cable driven throttle body is all that their software supports.
