20whp or so out of it and get me to my happy 350whp mark. do you think this is possible. going to still run 20psi, right running off spring pressure which is 16psi untuned but still pulls hard and sounds amazing.
If you are going to stick with 20 PSI, you are going to need to add timing and fuel on 93 octane. If you turn up the boost and add a bit more timing/fuel it shouldn't be far off from 350 on a Dynojet.... Get it retuned and re-dyno'd and let us know.
