Anybody have experience with the 411 PCM swap on the 7400 Vortec? I found a PCM in the junkyard but since it is my daily I haven't gotten around to swapping the PCM yet.
From what I have found BlackBear can flash the 411PCM to run the 7400 Vortec for roughly $250 then for another $100 or so you can get one of their cables (with a core charge) and actually record your trucks data and have them send you a personalized tune.
Alternatively I found a local guy that will write a custom program and dyno tune my truck for $450. I like the idea of seeing my truck on the dyno, but I also wonder how well dyno tunes translate to road driving performance. The BlackBear personalized tune is based on data recorded driving around on the street which seems like the best way to do it.
Thoughts?
If you just pulled the 411 out of a junkyard you need to have it tuned before your truck will run. If you swapped it then towed it to your local tuner he should be able to make the changes necessary for it to run, then dyno tune it, as long as he's familiar with the swap. What did you get the computer out of?
I'm sure blackbear could do it.
Street vs dyno depends on how much time the tuners takes to do it, and how good he is, they both SHOULD take the time to tune the VE and MAF tables. Then hopefully they both add some timing and change PE settings, shifts points and pressure, etc. The main benefit of dyno tuning is you can find what timing the engine makes the best torque at, this is a lot harder to do on the street.
Is your truck stock?
Edit 2: I didn't give a recommendation. If the tuner is reputable I would go dyno tune.
