Sell your vert and buy a TII if you want a fast car. I don't see any point in modding an N/A vert because it's always gonna be slow. Spend $5000 on a MoTeC EMS and it'll still be slow.

If i remember correctly when the VDI is "open" it's a shorter run then when it's "closed" (though I might have this backwards). Since they were saying that you need shorter runners ALL THE TIME then just keep the VDI to open all the time.
I do, however, realize that you will see substantial losses on a stock setup, especially at low RPM. If you go carb, you would have the same losses.

BTW, on piggy backing it to the ECU is it better then just have a fuel controller piggyback like an SAFC or E-Manage?

Iwouldnt reccomend using the MegaSquirt to anyone who cant even assemble the thing themselves!My MS total price so far:
MegaSquirt: $140
TechedgeWBO2: ~$200 (Optional
)GM HEI unit: $23
GM Air Temp sensor: $8
Throwing the AFM/TPS/ACV/RatsNst/Etc in the trash: priceless
Before MegaSquirt I was getting 28MPG peak with 26MPG Highway normal and 22-24MPG average. I'm shooting for 32MPG highway with water injection.

Also, nobody said you need shorter runners "all the time" and if you did they would be wrong. Changing the manifold runner length simply changes the rpm point at which VE peaks. The shorter the length the higher the VE peak occurs, which increases peak power but at the expense of low-end power.

My downside to an EMS is that i'll never be able to afford to do it right, so this seems like a way to get some decent cheap power, especially considering i know a mechanic experienced with tuning carbs. Plus it kind of adds to the old school feel.
BTW my mods are: HKS Sport catback, Bonez intake system, New Bosch plugs and wires, BFG G-Force tires. Soon getting KYB AGX struts.
