DU, I have Wayne's VCP stack injection on my 302. You will hear varying opinions about them. Many have had a great experience with them while others have gone mad trying to tune them and some have even given up.
On the positive side--the manifold itself, the hardware and the related computer gear is high quality. I have the SDS programmable ECU that Wayne used up until about a year ago. He has since switched to the Redline system which I have heard is an improvement from the SDS. The Redline allows downloading to your computer while the SDS does not.
After installing the complete system in my car during the build, the car started on the first try and ran pretty good, using a pre-programmed map that Wayne supplies based on your engine. It is very easy to get the car running so that you can cruise around. The hard part is getting it running at maximum performance.
Which brings us to the cons:
It is not a plug and play system. You will have to spend time, considerable time, tuning the engine if you want to get it running perfectly. If you use a dyno, it will go quicker but will cost a lot as you will need many pulls as you make numerous changes to all the different parameters of the programmable ECU. You should get a wide-band O2 sensor, which will allow you to monitor your air-fuel ratio without a dyno and allow you to make adjustments to the computer as needed. This will cost about $500.
If you are computer savvy and like tuning an engine, then you will love the stacks. If you just want to get in and drive and never have to fiddle with the car, the stacks are probably not a good idea.
You might want to call Wayne and see if there is anyone in your area with his system on their car, then you can see for yourself what is involved.
I have to tell you, though, that you just cant beat the WOW factor when you open the hood--everyone drools over these things.
Take care and if you have any questions, shoot me an e-mail:
