Short spurt of power. Drag use really. I have that on my Chevelle, but it is not as appropriate for a car like this. One that can really handle the turns and varying elevations at a race course, so well.
ZEX is the latest b/c of electrical tech in the distribution into the intake. It really helps you tune in the most appropriate amount, with relative ease and rather cheaply. I would go with that company and a A/F guage, and also oil pressure at the least. The kit should include the appropriate guages aside from the above to monitor the charge.
