Okay...so let me start off by apologizing for any and all errors I make during this thread due to being a "Noob" to tuning...with that said...here goes:
I have a 1965 Impala SS I recently purchased a crate LS376/525 engine for (swapped over all necessary parts i.e. fuel pump etc...)
I also installed FAST 65lb injectors and the brand new edelbrock cross-ram intake with twin 90mm throttlebodies.
The PCM I bought from a local tuning shop came with the appropriate tune to run the crate motor but my issue is that I don't have room to properly locate a MAF sensor so I have read about doing a "speed-density" tune...so I'm intrigued, yet, completely unknowledgeable about where to even begin with this. I purchased HPTuners so that I can learn the ropes, so to say, but I don't want to start messing with tables and such and detonate my brand new motor.
My main question is...due to running dual throttlebodies (I have installed a controller which syncs both and they are operating properly) along with the new injectors and MAF delete...where do I even begin with the tuning? I turned it over earlier and it busted off then immediately died and did the same thing 3 times in a row, so I paused to post on here and get some advice if possible.
Thank you for all your help,
Travis
