I'm good with that...i could've sent my car to a shop to get all this done but I enjoy fighting with headers and all the rest of the bolt on parts that gave me a fit. I know i saved a few bucks by doing it myself except tuning it on the dyno. Anybody want a 2018 Harley Davidson Street Glide CVO....just kidding...I WANT A DYNO!!!

I just bought a cvo break out..... Thinking about getting a glide

That’s about where mine was with just a Roto-fab intake. 10.9 or so. I was really surprised at how rich it was. As soon as I get my wideband up and running I’ll see how it is with the headers. I doubt it will be any leaner than high 11’s, but I’ll see soon.

Max torque guys 750 lb.ft

[Hheatt_ZL1]

Yep S.T.A.R.....TQ is 740 after the tune. The tuner was very impressed at that number.

What video?

I am not sure how you guys are getting away with these mods and no tuning. I put on a Vengeance CAI and everything SEEMED fine until I launched at a track. my 60ft went from a low 1.7 all the way up to a 2.8 on the worst pass (no spin either). I put the factory setup back on, and immediately went back to low 1.7 60ft times. maybe my car is just sensitive but it made a huge difference in torque management for me.

I haven't seen this here so here goes. Trying to stay away from a tune just in case I want to back to stock.

Will Rotofab, ported 95mm , Ported SC require a tune?

Even if everyone says yes I would still log it.

But if I have tune I would add E85 60% to that.

This should = 10s.

My cars a 2017 April production with A10.

According to Al O, any bolt-on will void your warranty. He specifically mentioned a CAI. I am fairly sure that doing a CAI and headers would cook your warranty to a crisp.

So you are making 750 rwtq with this combo after a tune?
You need to take this up full time as you are making about 100 more fp than the best shops out there with the same mods.

Yep and 670rwhp is pretty high for no tune...

They released a video when they debut the Zl1 drag car at Sema and said as well as pointing out on a sign warranty is in tact. I have posted the video a few times on here. Just don't have time at the moment to look for it.
