OK Boosty.
Find me a good Gen 3 and I'll swap it with you.......just make sure you port it first.

Wrong. I spoke with Brian a few months back. The price for recoating is posted here somewhere. I'll try to find it. CALL them after the holidays and tell Brian I sent you.

Whew, that'* good to know.

But maybe I'll like this new Gen V so much I won't ever want to go back to the Gen 3.

Some one might need it more than me.

........now back to the more pressing question of whether the PCM will need to be reprogrammed to compensate or will it learn by itself. :?

The GenV is just like any other device. It stuffs air. But it does it more efficiently than a Gen3. So you can run a larger pulley to create the same boost a smaller pulley on a Gen3 would.

Advantage? Less heat, quicker response to boost. I wouldn't expect any PCM issues whatsoever.

Remember I did a much more difficult swap on mine, and had no issues. I planned well though, and fully researched it first. The Gen2 to Gen3 swap is much more problematic than the 3/5 swap.

Personally I have read on the ClubGP and Regalgs Forums, That the Gen V can cause flow issues, I am not saying your car will not be driveable or faster but to get the most out of it a Powertuner is the next step you need to take Paul. Many Gen V owners use a Tuner to get the maximum out of they're investment. Again I am not saying it won't run but a good tune (more importantly with water injection) will net you more gains in the long run.

Hey Paul, how are your injectors doing? What did your old scans show?
The guy who has the Power Tuner that'* going to tune my 99 has a 98 GTP with a ZZP full intercooler, 3.2" pulley, Power Tuner, a cheap 3" PVC warm air intake and on the scanner it'* indicating his injectors are maxxed out. That'* a lot less than you have, but I'd bet he has a lot more miles. As far as I know he'* running stock exhaust.... including manifolds.
Upon hearing that I suspect I may have to upgrade to 39# Ford Lightning or 42.5# injectors, especially when I put my GEN V on.

Paul is on stock injectors (36#) but survives perfectly with them the same way I do. And his fuel trims are perfect, as are mine, and for the same reason.

The GenV MIGHT cause him to have to upgrade, but then again, it'* more EFFICIENT. Not necessarily more boost/fuel.

I was having fuel issues a while ago and solved it by simply upping the fuel pressure to the equivalent amount to equal the flow of 42 lb injectors.
The downside to doing that is it takes away my margin of fuel pump wear cause I'm up near the 60 psi max.

It'* Christmas Eve Bill.....can I open it now....can I ....can I.......

Don't open it, biotch. Not until tomorrow.

I've upgraded to a Walbro 255, but my stock fuel pump (in new condition) outflows the S2 pump anyway.

The Walbro may be all Paul needs, or the new one (non-walbro) that INTENSE sells now. A new fuel pump coupled with the FPR we run is a great combination for bumping up the fueling without the cost of new injectors or a PCM burn.
