Slightly new setup and street tune on the Honda. Butt dyno says she 💩s and gets!! We’ll see what the track says. Left some wiggle room for the fuel pump until/if I decide to upgrade it. 😏
Nice, mapping is the area I'm personally branching into more as of late. That and welding, I'm hoping to gain enough skills to be able to do a full project in my own.

Gotta love corn. I'm not brave enough to venture into custom mapping. I'm just running off-the-shelf tunes from Bootmod3 in my car. Been datalogging Stage 2 before I make the jump to Stage 2+. Got some very clean timing on my e30 run last night.

Oh I’m not that brave either. Here’s my tuner. Very well known in FK8/FL5 community. I think his latest FK8 setup has gone 10.1 in 1/4
Frank when I tune the Supra I plan on running OTS MHD maps. Can you run up to E50 mix?
I need to upgrade my fuel pump (again) if I want to run full E85.
You should be good for E50 mix on the TU pump(which your Supra should have). You'll need a downpipe of course to go past Stage 1. I don't have experience with MHD but I think they have either E40 or E50 maps or both. Full E85 I think requires a dorch pump or better and possibly a lift pump but I'm not certain.
I'm currently stage 2 with a catted downpipe, a TU pump, and a flex fuel kit(allows the car to detect the ethanol content and adjust the tune accordingly rather than selecting an E30 or E50 map and meticulously measuring my fuel to get there). I've also flashed the xhp trans tune.
All in I've spent probably $3500-3800 on mods. About $1k of that is labor because I wasn't interested in doing it myself.
I'm already at a point where traction is stopping me from using my full potential.

Yes I have the same AA downpipe you’re running. I do need a flex fuel kit. Heard good things about the xhp tune as well.
That’s why reason why I run my tank low in my Honda because it’s easier for me to mix 93/E85. Same with the Supra. A lot easier if could run full E but I’m not willing to take the Supra that far. After the tune I’ll probably consider it done.
Do not add up the cost🥴.
Just focus on the smiles and fun.😁
Traction is an issue. Can’t launch hard in 1st gear. 2nd gear launches. Need to get a wider tire it back when it comes time for new rubber.
We're supposed to have rain sunday into Monday and temps in the 50s, that will help. Its amazing though how firm the snow stll is, I can stand on it without pushing through still even after these warmer days
Those snow rocks are going to be here for a while. You ever see the ones in mall parking lots that stay there for months?
You ever use these salt off products that I see online all the time?

Oh I bet you will at some point, it's very addicting to be able to hand adjust your map to perfection for the exact area you live.
Plus you can tweak it if you go on a trip somewhere so you always get the max the hardware can offer at any given time. That's actually one reason I want to learn it so that on road trips I don't have to derate at all past what is absolutely needed for altitude changes, right now I need to drop to a 93 no E map and I lose 230whp from it on trips for the turbo car.
I also literally can't take the truck anywhere that doesn't have an E pump so I'm very much thinking of ditching the stock EFI and going with a fueltech for it as well as a ZF8 swap. Bellhousing is the exact same as any hemi so I can just slap a Trackhawk trans/T-case on it as long as the controller integrates correctly.

Come to the AWD dark side......you will be sub 10 sec 1/4 mile, the street with no prep.
It will ruin a lot of cars for you TBH, but in a way it also calms you down on the street because you know near nothing can touch you.
Especially in the wet if you are AWD, you don't feel compelled to race/respond to challengers if you are so fast it's just a waste of fuel to prove to them what you already known will happen.
Makes awesome side cash though, RWD hellcat bois think they have a prayer on the street and lose $500 on the bet lol!
