HP Tuners spark map for supercharged 4.0

[TrasH Hawk]

hello everyone so ive been messing around with my spark map making small changes here and there to the timing on the top end. I am running 4.0 that has been bored out .030 , mopar purple 229 cam (.440/.440), 1.7 rockers , shop 505 stage 2 pro-rock head (Ported,polished , 2.00/1.60 stainless valves, .580 max lift),Sprintex supercharger kit with 54mm pulley (10psi),1 step colder plugs,ported intake manifold, banks exhaust manifold , 36lb injectors , snow stage 2.5 methanol injection with a 2.5 nozzle on straight m1 ( i have been experimenting with boost juice , speed sauce and m1 mixtures. So my question is has any modified their spark tables on hp tuner if so do you wish to share some pointers? from what ive gathered the max ive seen peolpe show they have for timing is around 38 degrees. my stock map spikes to 41 than comes back down gradually and it kinda looks like my dyno chart so i was wondering if anyone could show me what i should be doing or provide me with some examples so i can learn for a jeep 4.0 thank you.

No answers but I do want to say kudos for all the hard work!

Thank you it's honestly my learned adventure into tuning and it's cheaper to replace a 4.0 than my sr20. I bought a tuner nerd v4 bought it wouldn't work for my setup. I'm looking to see if someone with more knowledge cares to pass it along.

Update , a fellow jeep owner sent me a picture of his spark map and I entered it into a new spark map. From the looks of things his spark map is slightly less aggressive and has a better curve for boost it would appear. I datalogged a cruise last night with a 2.0 meth nozzle in and it drove real nice there are some spots i need fatten up but I may throw the 2.5 nozzle in to see what that looks like first. I have noticed the vp m1 gives me slightly hotter iat's so i will probably give the boost juice or speed sauce another go.

Heres is my revised spark map gave it slightly more timing than the map i received. Overall I'm pretty happy with it i think I'm going to keep the spark map here for now until I can get a knock sensor detection system to verify my results, I will say I'm surprised these $100 pistons have held up to this abuse but it's been quite the learning experience. I'm going to look further into the power enrichment it seems to be set at 2500rpm from the factory and we are well within boost by than until next time maybe we will make more gains or maybe il get that forged stroker rebuild faster than expect.

This is super cool. I'd love to see a before/after spark map for a NA tune. I've heard there is a lot of room for improvement.
