Reading a lot here and on other sites, but still confused. Over the next year, I'm planning to install a low-mile $250 junkyard Vortec long block in my truck (1990 C1500 2WD) and keep all of my TBI stuff on it for simplicity. Everything will be stock...I'm not interested in headers, bigger cams, or whatever. I like the idea of the Vortec heads and factory roller cam for obvious reasons. I found a good deal on the GMPP intake too, but if it's gone before I can get it, I'll use a Vortec carb intake with an adaptor plate. Other tidbits I'll be adding include a Vortec fuel pump, and an adjustable FPR on a rebuilt throttle body. 3 wire o2 is going in tomorrow. So even though the long block will be stock, I'll still need a custom chip burned to take advantage of the more efficient Vortec design? Or will it run good enough to get me by? What is the best way to go about getting it tuned if it needs it? I am NOT fuel injection tuning savvy in the slightest, so all this talk about get this connector and this software and start data logging/burning chips is way over my head. This is also my daily driver so excessive down time is out of the question. I live in mid-Michigan if there's any old skool tuning folks in that area. I'll be honest, though I'm a 20 year auto mechanic veteran, this F/I tuning stuff makes me want to just toss a carb on it :/ I also considered a self-tuning stand alone system like a Fast or Terminator, but....more wiring, and more expense. I'm a fan of the TBI....cheap to fix, and it's truthfully all I need in this application.
