I was under the impression the charge air cooling was separate from the engine cooling system. But you state the intercooler affects engine radiator cooling. As such I wonder if there is a risk of having an always-on Prius pump over-cooling the engine radiator (which you don't want). Would like to know how that all works, if it is tied together or separate. I thought it was separate. (i've never bothered to look at the lines and follow them)

as far as PSI, you can't go off that. your car still thinks its making stock boost and will report as such on the cluster gauge. you'd need a real vacuum controlled boost gauge to get an accurate idea of what the actual manifold pressure is.
and no you shouldn't get limp mode as a result of the BMS box.

Modification: line from the stock pump goes to the top coolant connection of radiator, the lower connection of radiator goes top connection of the aftermarket HE, the lower HE connection goes up to the Prius Pump
the HE and radiator is one piece but the coolant passages are seperated thats is why the HE has its own coolant reservoir...

your car (in my experience) needs time to adapt to make full power. give it 2-3 days. even a week.

TTi STAGE 2 PLUS Tune: I don’t know how accurate the boost gauge but it jumped to 32.5 psi and hold it at 26 psi at full throttle. With oem boost gauge it show all the way to the en d which i have no idea...
TTi STAGE 2 PLUS Tune: with after market HE intake temperature drop from 99f to 88f (yellow line).
Anyone use OBD Fusion for data logging?

@mvaldez Can you take a picture of the sensors you are connecting to? The OEM boost gauge will read the lower boost value that the piggyback is sending to the ECU. Plug it back in and drive it around for a bit, you should feel a difference.

Hi pnoygil, when you said ''lag is almost not there'', as the ''lag'' is when for example doing a overtaking , smash the pedal that 2 sec lag? If the tune can remove that, I would be very keen to explore with Tony
