Not likely to go SC anytime soon, was just wondering if I actually need both plenum spacer and mrev2 as I will uprev again when I have decats fitted so would've removed one of them.
When I had uprev last year at hdev I asked about headers and funnily somebody had them fitted and made not even 1hp, i've quite in a few forums apparently the stock ones are actually pretty good.
Admit I've been put off throttlebody now

de cats are hit and miss most wont give any hp gains more an increase in torque tho talking minimal tho decats are just a quick way to make it louder
