914 ITB's, Pro's and Cons, option opinions and show us your setup!! Options

It seems like ITB's are all the rage with our air cooled sixes.
The throttle bodies are either PMO or direct to head either with butterflies or AT-Power with no butterflies.
Mark dug up some of the pricing!! Thanks Mark!!

Lots of options which can raise or lower the price.

I have a stock Euro 3.2 with DME that does run fine, but I miss the sound of the webers, but I don't miss the hassle of webers, cold start, poor gas mileage, etc.

I know ITB's are expensive, but option 2 at X-Faktory is not that bad and pretty popular over on the Pelican 911 technical forum.

Anybody on this forum have any experience with any of these toys?

I purchased VEMS for my 3.2 but haven't installed it yet. It doesn't change the look of the induction, just modernizes the electronics and programing and is plug and play to the existing wire harness.

What does it include? There website is horrible and I don't see any installation manuals. I also have a mustang MAF with adapter that works with stock DME. I noticed a small uptick with wide open throttle. Otherwise at low RPM's it didn't do much. In Bruce Anderson's book he said a MAF is good for around 10hp, chip for another 10hp and better exhaust for around another 10hp. I already have a Steve Wong chip and ben's heat exchangers. The chip and ben's heat exchangers have been the best improvement so far.

I purchased it through Peep, Raceboy on Pelican. He builds a wire harness for it so it can plug into the stock 3.2 harness. I mostly purchased for a custom 3.2 I'm building with hot cams, 3.4 cylinders, max moritz pistons, higher compression, etc. It uses the stock 3.2 reference sensors and modern injectors.
I don't think the FI adds power but will be very tunable to let the engine achieve it's best results. It was ~ $1,200

It sounds like you've already attended to the low hanging fruit with the chip and exhaust. While you might see your engine as a bit boring, I would be really hesitant to touch it. One of the best things about a 3.2 is it's "boring" ability to start and run smooth and dependably when you turn the key.

Sum of the parts, the mechanical stuff...the cams, pistons, CR, intake, exhaust, etc, this is what will bump the HP.
The FI is just what runs all this new kit.

It should be a healthy engine Mark.
