Went through it with GM on my Vibe, added, GMPP S/C, engine rod snapped, took it to dealer, dealer refused warranty. Went all the way up to GM, they said if it is indeed a GMPP AND was installed by an authorized installer, THEN it is covered, if not, you my friend are assed out! $900 and some hrs work later I had a new/used engine with less miles than mine had on it (22k!). I had to by the engine from a CorollaS at a local yard and un/install it myself. They would not touch it under warranty.

 

Could you please also inquire about the HP and torque ratings on the auto.

Thanks!!

 

My thoughts as well. You can't take 260hp to 290 when you don't have 260 to start with.

So 235 to what?

 

Very interested. I've heard the PCM flash associated with this upgrade eliminates the current 255 kPa code limit, thus allowing for control of greater than 22.5 psi boost.

 

Opens up some interesting possibilities eh?

 

Correct assumption. They themselves would have to eleminate the ristrictions. I have a feeling that it's a Program, Piping, and Filter change. Should cost about $600.

 

They'll need some kind of piping change as the plastic one leading into the intercooler looks to be a weak point (also the non-clamp clamps they're using are as cheezy as they get).

I can see some nice options with the 255 kPa cap removed, then the Hahn tune as a new baseline and then the HPC on top of that to do your own mods from there. Gets expensive, but a nice tune could be had.

 

Looks like this will be a "High Pressure Fuel System" upgrade with a different fuel rail assy. and a few other minor pieces. I have a few part numbers but almost no real information. Stay tuned.

 

That surprises me as the current fuel system is in the 1200+ PSI range.

 

This surprises me also. Injector duty cycle's are currently super low, leaving plenty of head room. From what I've seen so far, the stock fuel system has no issues keeping up with the current 255 kPa limit.
