Wow! I don't remember seeing a 50 HP gain from a manifold & TB
swap before. Don't remember seeing a 2nd Torque hump like
That NA either, What did the tuner say, what are cam specs again?
Reasons for not going to, through 6500 RPM? Is the dip from
Letting off @ ~6200 ish?
Great results! Must respond like a beast.

And plus I'm still getting 26-27 MPGs at 75 mph rolling down the freeway at 2 grand....love that plus too
This shop doesn't seem to hook up to a plug wire; so I'm thinking it's getting RPM from his lap top.....IDK
The first pull this time was 454 and it sounded like it floated at 6900 but was apparently going lean.....duty cycle was like 77% on the first set of pulls back in November. He added roughly 10% for the second pull and it sounded clean and mean to 6500 where he lifted and then it swung up after that.....graph is weird to me too though......like even if you visually extend it out it should be in that 440 range which was my original goal for this project.
Cam is one that I picked from Texas Speed's website when they had a Christmas custom special in Dec 2014 for $350....So I basically copied Tooley/Martin/Tony....etc. with a 226-.606" intake lobe and the 232-.575" for the Exhaust side and with a 114LS @111ICL this thing idles very stealthy at 900 with ZERO bucking ever........really quite smooth IMO
Now I just need to get the ET slip to prove my *** cheek dyno feeling of 10.80-ish @ 126
