a AFR gauge is a must, when u get it ,u may have to remove your fuel/filter/regulator (all in one)and put in a adjustable fuel regulator don;t forget it will not work with a return line then u can replace your lower crank pulley with a 180 or 178 along with your SC pulley and get about another 40 to 60 HP with the afr guage the best number for the street is 12.3 remember you are only at 12.3 at wot in 3 ,,4,,and 5 gear

So:
- AFR gauge w/ boost connector (~ $427)
- Adjustable fuel regulator ($260) https://www.needswings.com/needswing...sure-regulator "This is not to be used with the factory fuel filter/regulator." < with? So I guess as a replacement, ofc.
- High flow fuel pump ($323) https://www.needswings.com/55-fuel-pump
- Upgrade crank pulley (??? from where)
- SC pulley upgrade? This is already a 65mm Eurocharged one

What is the effect of your bold text: don;t forget it will not work with a return line ?

Maybe I am not following this correctly BUT, the SRT-6 is only available in the auto transmission. I haven't seen anything referencing a drivetrain conversion here.

They are handy in determining if you are consistently running rich or lean.
Looking at my exhaust and gas usage, i think its rather rich at the moment. Last mod was the oil catch can and when I had put the wires on, I took pictures of the intake. There was a bit of oil, but nothing too crazy.
After a week I removed it again, and there was substantial more oil in it, only on the right side.

Apples and oranges, you posted a reference mentioning something about a 'manual'. Did your post mean a manual transmission? If not, PLEASE explain what you meant here ( ...Do you think the standard is not capable of keeping the wheels straight with so much power on the regular diff?...). Your post 19 referenced, if you misspoke then OK .

If you mean the words "standard" and "regular", they were both about the same thing: the standard differential on the SRT-6. I can expect that its made for usage with < 300WHP, and if you go higher it starts being unable to keep the wheels from spinning and making the ESP kick in.

sorry (((without))) when u temove the filter/regulator and install a manul fuel regulator u have to have a return line
Upgrade crank pulley (??? from where) ------- needswings
- AFR gauge w/ boost connector (~ $427) -------that's is high unless it is installed
High flow fuel pump ($323) ------- u said you already have a sl55 pump that will work.
SC pulley upgrade? This is already a 65mm Eurocharged one ----- that should be fine
u will have to play with fuel pressure to get afr's where you want them about 65 psi

on mine i have the vacuum not conected

Alright, so you have an additional line to install (not just replacement of the current fuel filter/regulator). Fair enough.
I can't seem to find a crank pulley upgrade on Needswings without buying the complete set with PSK and such. I guess @NeedsWings removed if from the website? > https://www.needswings.com/asp-178mm-kit-psk178
I have not bought a new/upgraded fuelpump (yet).
The AFR gauge pricing was based of Needswings' set:
https://www.needswings.com/zeitronix...and-controller 272 + 124 (boost/vac sensor) + 4 (o2 bung) + 27 (wireloom kit, because nice)

I see your edited post, so this is just an more aftermarket AFR sensor I suppose? More info on what you've got?

With my mods, and the best tires money can buy short of slicks, I still find it super easy to spin the wheels even in second gear - WITH limited slip. I don't know your car, but I know mine. Before I had LSD, when I was making a left or right turn after a stop light, it was dangerously easy for the car to fishtail its way around the corner while at the same time the "electronic stabilization control" program was doing its level best to compete with my attempted control inputs - truly spectacularly horrible. All fixed with LSD (not the drug). Expensive but beyond worth it.

An LSD is an interesting mod. Do you think the standard is not capable of keeping the wheels straight with so much power on the regular diff?
A new fuelpump should be doable. Any tools to figure out if the fuel ratio is OK (through obd for example)?

Thanks
