What's everyone's thoughts? Will be dropping in the vortec 383 in the next week or two and will be ready to run it soon. I have a "starter" chip burned for me by Dave W, Old School EFI, while I was watching, that should let me get it running, but it will need additional tweaking to the fuel map and timing tables. Starter chip only cost $35 but the price for the full tune based on Tuner Pro RT data logging is $250. That was my original plan, but while I was there, Dave actually encouraged me to consider doing it myself (even though he'd be out that business). So..... Option 1 - get it running and gingerly drive it over to Dave's house (25 minutes) and pay the $250 Option 2 - purchase a Moates Burn2 chip burner for $85, and give this a go. I already have the ALDL to USB cable, a laptop and the Tuner Pro RT software. I Would make extensive use of the many different resources available on Gearhead-EFI.com. I'm reasonably competent around computers, lots of experience with Excel (used fairly heavily in this process) but I'm a chip-burning and Tuner Pro newb. Want to learn, though! Especially interested in opinions of those who have tried this, with good or bad results. Long story of my build here. Short story here: 383 stroker, rebuilt 062 vortecs, GMPP q-jet/vortec manifold, 9.5 CR, converted '90 4-bolt block to roller valve train with parts from L31 core motor. Cam from L31 (no debate here about the cam, I know many think it's too small for a 383). 46 mm bored SBC throttle body. 70 lbs/hr 454 injectors. EGR deleted (already removed in starter chip).
