Just talked to the engine builder. He said that the car is ready for break in, but still has a few small bugs here and there. He also said that acceleration feels like nothing is holding it back, feels very stout. I told him to just finish the car, break it in himself, tune it, and give it back to me when it's ready. He's got two weeks.

Supposed to get the car back tomorrow, dynoed, ready to go. Will still have to do break in for another 500 miles after I'd think.

Tomorrow. It's getting dynoed tomorrow. So tomorrow either one of the following things will happen.
1. I will come on here posting happy about how the car made more power than expected
2. I will come on here posting in whatever mood if the car dynoed 350whp on the dot.
3. I will be convicted of murder in 2nd degree because the car made 290whp!!!

I'd be pretty happy w/ 350whp. Looking over your combo the *only* things that *might* hold you back would be the head/header combo. But the heads really seem like good flowing units, the headers aren't THAT important (I mean, Long tubes may make another 15hp or so), so I'd be fairly confident you'll hit that number at least...

290whp is only 70 more than what I dynoed last. And considering how much I've spent, that would be a joke. I told the builder that I wanna see 350whp at the very least.

Has the OP killed himself after seeing the dyno numbers?

Ok, so the car is tuned for break in, and with safe tune it makes 308whp. Timing is still low (27 degrees) and we are reaching the limit of MAF voltage. I'm going to break it in for two weeks, and then return it to button up all the stuff, give it a final tune, and get the car back perfect.
First impressions. The motor is a LOT more responsive. Responds to throttle a lot quicker than I'm used to. Cam idle is actually pretty good, does not shake the car like expected. Acceleration at partial throttle is very smooth and super easy. I gotta keep an eye on speedo to make sure I'm not going faster than I should be.
Some issues. Car does not like to cruise below 1500 rpm, bucks around a lot. I don't know if that's the tuning issue, or something else, or maybe the cam itself, but that's something I can live with. At wide open throttle timing changes, and the car jumps around a lot, that's something that needs to be sorted out.

308 @ only 27 degrees timing is actually pretty dang good. You'll probably end up at 34 degrees and, along with other tuning changes, hit your target at a minimum.
That's what I'm hoping for, because the tuner made it sound like that's it and we are not going to make more. I was really pissed off. Then he explained a few things, I came down slightly. I may have to go to a different shop that will tune the car properly.
Yes, dynojet.

Well, 27 degrees is AWFULLY low with a cam like yours...and a fresh engine is usually "tight"; Most every engine I've done, I always end up adjusting the idle speed down as the engine breaks in. That could be robbing you of quite a bit of power right there...
Likewise, dyno's are just that....tuning tools. Different dyno's give different results, sometimes the difference is substantial.
I once helped someone put together an engine, and he used one of my recipes. He wanted an engine that made ~400-450hp,and not WHEEL Hp, just Hp. From a small block that had power brakes and an automatic trans, 4 speed auto @ 3.42 gears, in fact, I put together what I thought would safely give him the number he sought while still making MORE than enough vacuum to work with the power brakes AND be able to more or less idle down the hwy at 60mph at only 1800 rpms...WITH a carb. That's not the easiest thing in the world to do.
Put together a 9.5:1 383 SBC w/ AFR 205's, lunati voodoo cam (230/238, 110 LSA), eddy performer rpm, eddy 750 carb, long tubes, good ignition, etc.
Car was more than stout, did everything he needed...and he seemed really happy with it. Till he dyno'd it...only getting 306whp with them not pulling it past 5500 because of a problem they were having.
First, pointing out that had they wrung it out, yes...they'd had made a good bit more power. But then it was like, Hey, the car feels like everything you wanted...and does it too. Doesn't mind low-rpm jaunts on the hwy or cruising, gets good mileage on the long cruises/tours he likes to do, and beats MOST cars he encounters. It's like, why care about a number?
27 degree's just seems soooo low...even if it likes 32 degrees max, it should still jump quite a bit in power.
Now, if after a while, final tuning etc you're curious, or it doesn't take too many more degrees advance...do a compression test. That thing might have cylinder pressure through the roof, in which case the cam might be installed w/ too much advance, OR, you might want to get a bigger cam and a tighter LSA...

i don't believe in engine break-ins, but only my opinion though.
wewt
also what are you guys using to tune SCT?

So I threw the car on the scale. It tipped it at 3380 lbs, meaning that I've lost about 40 lbs. Not a whole lot, but considering that almost everything in the motor was bigger and beefier, I'm not surprised one bit. One thing that did surprise me was the front to rear weight distribution. Car went from 57/43 to 54/46. That's 3 percent better. I'm pretty impressed.

No idea. He's welcome any time though. Really need to focus on driveability of this car damn it. Driving in traffic is a bit of a handful, since tune has some missing stuff in it.

I've made a decision to switch shops for tuning. Taking it to a different shop tomorrow after work to find out what it needs to get a good tune on there, and finish all the work.

I have no idea. He didn't have the print out at the time. I'm sure he didn't tune the low end on the dyno.

I can has daily. Bought a 2005 TSX today. Good to know that I won't be bothered by how ridiculous the mustang is on daily drive. Car is getting done little by little, should have it back end of next week.
