You're still comparing a twin turbo 6 to an NA 6. Of course you'll make more power by upping the boost. But 340 whp on 13 psi Vs 320 whp on 0 psi (full bolt on Z) isn't saying much. BPU++ supras will make 450 whp on pump gas with similar boost and you dont need to upgrade fuel pumps, etc. I'm just saying, the 135 and 335 are nice cars and make a ton of power with a simple ecu flash but it's not exactly a marvel of engineering in terms of reliability with said upgrades. But if you upgrade the fuel pump, exhaust, and intercooler than you'll have a more reliable way of making close to 400 whp on the stock turbos.
