New Garrett GTX2867r

[BlackZenkiS14]

I am on 93octane, 740cc injectors, and 50/50 meth water injection with a 7gpm nozzle.

Still a little lean up top for my tastes.

I wasn't able to watch the wideband inside the car, because I wasn't allowed within a certain area around the dyno for safety.

But the dyno operator (driver) said the wideband in the car looked healthier and safer than the dyno readout. But didn't get into specifics, as this was just a quick dyno day, not a tuning session.

In my experience my in car wideband always reads richer than the dyno wide band that's such in the end of the exhaust pipe. But not by a whole point or more.
You should consider going to a M10 jet over 400hp and use strait methanol.
Methanol and water don't mix so your not actually spraying a 50/50 mix.
