will you be doing a before and after dyno with stock tune ? then a tune and dyno after the bigger parts are installed?

At the moment I’m running bully dog bdx...I know, I know, this isn’t the best option but i do plan to get it professionally tuned/dyno’d. Fun fact about the bdx, when I bought it it wasn’t compatible with my truck. I actually had to talk with bully dog in Texas and they had to make custom tune configurations for me. It took them about a month🙄. But I can definitely tell the difference. Haven’t had any issues for two years now. 
 

Is the tune needed for the l86 tb/mani swap? I heard some people haven’t had any issues.  Not sure if it would have an effect on the bdx or not

In the tune.

 

i mean the maf should be able to compensate for most of it. forget all my tuning stuff. 
 

might just need a tune for open loop

Oh ok. Got it. I’ve heard some guys have said they were fine without the tune. I obviously want a tune but until I can get one, it’s nice to know if the truck can function without it. I need it for work etc

if you want to just pretend to make power, then honestly i would just do a larger throttle body for the l83 manifold, if your not gonna tune it.

 

if you go the whole L86 induction then you might as well do it correctly and install a stage 1 or 2 cam from BTR, then bolt in the lt5 TB with l86 mani. ported or not.  then you'll have a good starting point to go from. and real seat of the pant ride.

I got my parts from rock auto. They came quick but the intake manifold has a cracked port from shipping. 😩. I’ve emailed them yesterday and filled out a replacement form. Hopefully I hear back soon. They’re usually pretty good with this stuff
