Looking for tuning help on 1996 Bronco
Posted: 2022 Feb 11, 09:05
Howdy folks -
Last year I swapped a 427 in the place of the worn out 351 in my 1996 Bronco. I added the standard stuff - intake, headers, exhaust, etc. I'm using the factory Ford EFI and programming. I upgraded to 30lb injectors and a calibrated MAF from PRO-M. Overall, she is running good, but I haven't gotten the timing dialed in perfectly as I can still hear some pinging in certain situations. I haven't touched the tuning but feel that I'm probably leaving some power/effeciency/driveability on the table. I don't know much about tuning, so I'm hoping that y'all can educate me a bit before I take the plunge (want to make sure this is the right direction before spending $$$).
I reached out to a couple of local(ish) shops last year after the swap only to find that they were backed up several months. Since they are all 50+ miles away, I didn't press or stay in contact because I basically didn't want to have to go there multiple times to get this thing dialed in. After dpoing some more google searching recently, I stumbled upon this site and am intrigued.
Thoughts on how y'all could help? What should my expectations be? I don't know much about the internals of the engine (I had it built... I do have the cam specs and calibration sheet from the MAF though) nor how much power it makes. I've read through a lot of the getting started stuff on the site and most doesn't apply to my situation, but still think I could get something out of the motor with some custom tuning.
I'm all ears and am ready to learn!
