Exactly Andy!
As explained in my post above to clarify this confusion, reflashing the ECU does not reset the TPS

Superman you really need to have this done on your ski as its quite apparent that...

No it does not!!!

Setting TPS must be done with BUDS or Candoo diagnostic software.
You will set idle position and full throttle position with the diagnostic software.[/QUOTE]

Jonatan did...

you installed a new 02 sensor but did you do a free air calibration of the sensor before putting it into use?
follow the instructions that came with your AFR gauge and do the free air calibration....

I installed a new O2 sensor couple days ago just to make sure the gauge wasn't screwy. What does the TPS recalibration really fix? How would I know I need to get that done? Seems like a pain if I...

Correct! The stock injectors are at max duty cycle at over 15 psi boost pressure and 8500 rpm[/QUOTE]

Just sitting at idle my fuel PSI is at 72lbs with AFR 13.8. No boost in the equation....

I agree. Some changes need to be made to the tuning.[/QUOTE]

I still also have the issue between 7800 and 8400 where the fuel richens up and AFR's go from 11.9 to 10.3 then back to 11.9 after...

Can the stock pump even keep up at 78lb? correct me if am wrong, more psi= to a rich condition vs low psi less fuel lean ?[/QUOTE]

I don't have a stock pump, you need what ever PSI to keep your...

one more question i got vtech tune for 8800 and 50s but i get readings of 15-17 on idle but give it gas and it becomes richer drops to 13-14 is this normal or i need a revised tune from...

I had to reread your post twice...but I am confused. Are you saying the new 2013 intercooler does not fill your catch with water, but the 2012 did? Is that what your trying to say?[/QUOTE]

I had...

I already had my intercooler replaced under warranty and my catch can is filling to top with water after a days ride again. Most people are not going to notice the intercooler leaking unless you have...

Right now the 8350 Beta Tune, but it does the same thing with all the tunes that I have tried.

What do you mean by screwy? You talking about the video refresh rate?

For you guys that have AFR gauges on the 2012 PX, can you check and see if your fuel goes rich around 7800 through 8300? All my vtech tunes go from 11.9 to 10.5 back to 11.9 around those RPM's.
I...

Just tested the Beta tune today. Didn't go into Limp Mode and the midrange has been improved.

Hey Eric,

Good to see your doing ok. We will see you soon :)

Just water. I'm running a fuel regulator. The bow will bounce up and down with low fuel and VTS all the way up but no bucking yet.

Not sure what pump stuffing is. Went from 76 to 79.0 on Garmin GPS with sponsons on middle position.
I also replaced the prop at the same time with the Solas SRZ-15/20r and pitched to hit 8720. ...

Troy's waiting on the Athena :) I have the et137 4mm on mine. Went from 11lbs to 14.5lbs at 8600.

I got the same email. Downloaded the new map but haven't tried it yet.

Sounds like your not in Sports Mode. Also make sure the VTS is set in middle or below during launch.
That way you don't jump out of the water and loose your traction. Like Troy said, after 5 hours...

Mine looks fine so far.

Fun times

It was pretty much even the way out but giving it was my first time ever doing something like this against someone who has raced a hundred times, I think I did pretty good.
On the way back no one...
