is heard that if you have a vtec engine and you go boost you have to turn vtec on all the time or turn it off or else u lose power... is that true? sry to jack the thread

if you want to run 20 PSI on any honda block you better rebuild. forged low compression pistons, forged rods, cylinder sleeves or block guard etc. Open deck engines will not hold 20 psi very reliably; if at all. And with 20 psi you are gonna want something really good and accurate to tune with. I have a greddy e-manage with profec e01 boost controller and wideband o2 sensor on my eclipse and works great. But it also runs great at 22 psi with stock rods and crank
