Thanks to Trebila, I am tuned! Now I just need new plugs. The old Bosch plugs weren't cutting it, and I was having misfires at WOT. NGK iridium plugs will be here by the end of the week and hopefully It'll fix the issue and I'll be able to do a few more runs to get my tune dialed in!

assuming you have the correct spring, the bov noise is intake related.. it was prominent with my DCI but then I installed an upgr8 drop in filter and viola the sound is basically gone (audio off HVAC off and you can hear it very faintly). it's annoying but that's one of many reasons I ditched the DCI lol.

As long as its not hurting anything, I'm fine with it. (I've been told by many it's harmless) but I still would like to know what actually causes the sound. Not going to ditch my inlets, as putting stock ones in would be impossible.

Along with the Hexon's, I am also going to be installing a Wagner II Competition FMIC, and replacing my Vishnu OFT with a JB4. Lastly, inlets and Outlets.. I am still on the wall about which brand to go with, VRSF or MMP. I would like to relocate my air filters to the passenger side, but I'm still doing my research as to which brand has better fitment and kits. I plan on doing the surgery myself, along with a few other car enthusiasts I work with. My questions and concerns are with spare parts, tools and other things I should have ready at the same time I do the swap. I plan to buy (or build) an engine support bar, for dropping the subframe, also buying fluids to do a oil/ coolant change at the same time. Any other suggestions or input you guys can offer? All is appreciated! I'll keep the thread going as soon as the parts start flowing!

Small torque wrench used for motorcycles....

And a large one

Digital ones are nice to have

Swapped out my old Bosch plugs today with new iridium NGK plugs, much smoother idle and acceleration. Still have a slight misfire/ stutter at wot, with codes.... Next step will be a walnut blasting.

Took off my old stale vacuum lines and replaced them with some high temp red silicone. Should put atleast 20+hp to da wheels..

Most recent update to the build!! Walnut blasting done and a little bit of wire tuck, engine bay cleanup. Ran the ugly cowl cables along the firewall. Having an occasional misfire at wot. Gonna wait for the code to pop back up to see which coil I need to try and swap. Tune is still being adjusted... Dyno will come soon!

Fixed the misfire for now.. Looking to buy myself some methanol parts for Christmas and am a bit stuck on where to begin. I want to do port methanol directly into each cylinder. This means 6 injectors, all connected with SS lines to a distribution block. Does anyone have any good information on what size injectors to use? Ive heard of using check valves, to prevent leaks.. do I need 6? Do I need to run 2 pumps for larger injectors? My target is 600+ HP. ANY info is appreciated. Thanks!!
