Stock MT is 1second faster 0-60 vs auto, 90% because MT can launch at much higher RPM. But both taking off from idle at same rpm MT is only .1sec faster.
But once you are FI and become traction limited that launching benefit becomes less and less beneficial unless your on slicks on a prept track. Otherwise you just sit in place spinning.

I do plan on building my trans, valve body, clutch packs, and torque converter, i could then launch at 3k rpm but again traction is already a problem.
I do think about replacing the header this year. It's closer to Japan, Maybe TOMEI 4-2-1. I believe it will make a difference. So good with no cats.

Rear wheel drive.. Traction is inevitable. I heard people say 350P Is the max power that the auto trans can withstand. The stock manual trans is lower then AT. So the gearbox upgrade is a certainty. My AT gearbox smells like BBQ when it's speeding up at high RPM. Trans really need to upgrade.

Vehicle weight 1.2 tons. Over 270HP(I guess). Only wider tires to enhancing grip and control. CUP2 or RE11 tires. I will change MichelinPS4 in winter. But I feel it doesn't grip as much as the TOYO I used before.

May I ask if you are teaching ECU by yourself? I need to go to a professional store for this. It costs about $1,000 per visit...

Manual is rated at 180ft lbs torque before you need a clutch. Then 240ft lbs before gears shear. Auto is rated at 220ft lbs. ssp valve body and ssp clutch pack brings it up to 400ft lbs. Plus the valve body helps with quicker firmer shifts. Stock stall converter has a brake stall of about 2400rpm, ssp stall converter has brake stall of about 3100rpm. Transmission cooler also helps trans longevity especially with lots of extra power.

Yes traction is an issue once boosted. Point was because of that one of the main benefit of manual transmission is negated.

I am E-tuned by xero-limit. Im pretty sure you can get an E-tune from many different tuners.

IC kit still for sale. Would love to get rid of this thing. If you're chewing on it, make me an offer.

Yes still needs to be cooled. Breaking a limit will soon meet a new limit.

It was something we developed here in the UK, sold by Abbey Motorsport so common on UK cars:
Replacement MAP sensor plate for MAP and IAT sensors.

Are you Intercooled and/or E85?
What MAP sensor is that?
Did you find a maf harness that splits to IAT connector so ecu IAT reading is from that instead of maf sensor?

EDIT: Never mind thats probably the IAT sensor... But i was reading that it either A. picks up the temp of the plate and not so much the airflow so reads a false high or B. if its far enough into the air stream it will read accurate but blocks and interrupts airflow

IAT relocation is just as easy as cutting the first 2 cables of the maf and solder them to a new iat sensor, I did the same on my hks v2 sc
of course then you should use a new scale that suits better the new sensor

So I discovered soot on the underside of my car hood. This is most likely from the leak that I cannot find. Anyone know where I should start looking? I heard something about a leaking PCV, but I have no clue where/how I should check that..

What kind of SC oil are you using?

Redline 75W90 I believe. It's Redline 75W?? for sure.

Not sure if the SC oil is making it black... it might be something with my PCV hose or exhaust leak.. either way this is frustrating.

I am with you. Fighting this lean condistion plus the inconsistent performance is frustrating. Keep trying. I am looking at borrowing another stock MAF, also looking at DI seals for the p0171 code along with any leaks post MAF. Also going to order a new SC gasket. If not I will probably remove the kit, sell it and stick to NA for a while with e85 and ecutek

The frustrating part is these mods are still not in play on any of the current sprintex platforms. Including the Jeep units. Jon tried working with Sprintex and it fell on deaf ears. He has bought out all remaining parts that were out in the field. My suspicion is he will probably start making these replacement parts as needed. I believe he is the only person in the world that has actually seems to care about Sprintex customer base even over the own damn corporation. They had a lot of good people leave. There customer service here in the states is about as good as HKS US customer service which blows. Thank goodness for Jon Bond. He will keep these units alive for a good while.
Do you remember if your unit threw any lean codes with the leak? I have the same leaks as you did but they sure as hell do not look big enough to throw my fuel trims off by 40%.

IC'd, no E85 here in the UK. IAT disconnected at MAF and extended to the sensor on the plate, as you stated. Not sure if I have a picture but my tuner is experienced enough to ensure that neither A or B is an issue. It's a wire type sensor which does stick into the manifold a little but not much deeper than the recess for the plate on the runners. Reacts fast enough to be air temp, both as temps increase and decrease.
