From what I was told, the injectors are a good match for the other components. Hell, I thought 60lb. injectors were slight overkill. But most people run the KB Mach 1 kit on a stock motor, so it's never pushing more than 8-10lbs. of boost. I wanted to bump that up to around 16+lbs. so the shop guys, who do alot of KB and Whipple installations, said that since they were working with a clean slate, they wanted to make sure nothing was going to get pegged and cause a redo down the road. So far they haven't been wrong. I haven't been in for the final tuning, hopefully by the end of February, I'll have those numbers published.
So far, from what I hear abotu your shop, I'm liking them. Alot 'subpar' shops out there now-a-days.
IR you stating you had stock exh. manifolds, and I was wondering if you were going to swap those out. You haven't touched the heads either IIRC?
99_Z28s car just wasnt' setup correctly.

I've always wondered how these bolt on cars, or even 450 RWHP cars get zero traction. I hook just fine in 2nd on the spray as long as it isn't ridiculously cold outside. 275 GSD3 street tires and 3 point weld-ins. From a stop I struggle in first though.

I had BFG G-force on my AB procharged mach. Burn outs had to be done in second gear though......It really just came down to me feathering the clutch correctly. I had a perfect launch on a december night against an Evo. I outlaunched that fugger pretty good. That was after he pulled a ricer launch on me. (not confirming a race). I went sideways into third catching up to him.....LOL

is that I want Kooks headers and it'll require that I hack up
my (expensive) x-pipe.

Holy ****! You's are running **** I haven't even heard of, in cars that are faster than I have even been in! lol 
(I feel even more like a newb now-if that's possible on this site lol). Unit213-what et and trap is your ride? That thing seems damn crazy.

For example, I have 400/367 to the wheels, which is nothing crazy, but I have 4.10s and an MN12 trans with shorter gear ratios. First and second are useless on the Nittos if it's below 50 degrees. Above 50 and first is still useless - in fact it's always useless unless I'm running the ET Streets after a burnout - and second is questionable unless I do a burnout or start in a bad spot. I would say in normal 70-80 degree weather during the Spring, Summer, and Fall, second hooks 2/3 of the time.
If I was running a stock transmission and 3.42s or 3.73s, it would be a totally different story.
Think about riding a bike on sandy pavement and trying to pedal as fast as you can. Whether you're in one of your lowest gears or highest makes a huge difference and will make spinning that back tire a LOT easier in the shortest gear.

I know what you mean about hacking up mids. Some people forget about that part when going to LT's. Still have the stock H? You could just order in some high flows and cut them in. It'll even increase a tad bit of back pressure. LOL Or just order a new mid, and not touch the high $$ one.
What gearing are you running? It makes a HUGE difference.

I had 3.55s. I was thinking of 3.73s or 3.90s down the road. 4.10s+Blown+3650+DD = not my thing. LOL

Nope...no roll bar. It's all street car.
Twin Ford GT pumps.
I'll have a similar setup. I already have the mods.
The tune is safe, but I'm pushing it to the brink for sure. Did I mention
the stock exhaust manifolds still?

Well, there's only one option left before an aftermarket blower or a turbo (both of which will put you well out of reach of my car), and that's a port. If you port it, it might be worth getting together still, but if it's something bigger, I'm not gonna waste my gas - I'll have to grab a friend with a faster car and take a ride up with them 
.
Keep me posted when you do hit the track.

Nope...no 9's. I'm out of fuel still, but I have all the fuel system mods. I
just need to install them then throw a tune in the car. I'm running 23psi
on stock pumps right now.
We'll see how she runs this year with
some slicks and a healthy shot of sauce once I get the fuel system done.
Here's a setup for you...23psi on a 2.2L KB, 110 race gas, 22* of timing,
stock fuel pumps, 55lb injectors, stock feed line, BAP, etc.
Now you see why I can't make anymore power until I upgrade the fuel system!

I wouldn't expect any well-driven ported or more Cobra to be running 11s unless it wasn't setup right or on crappy tires. But we both know your plans involve much more than a port.
I personally would love to have a 10-second slip sometime this year if all the plans go through and I spoil myself a bit more than I'm used to, but I may have to hold off on part of my plans since I'm trying to get the car paid off in the next couple months. I'd rather have an 11-second title in hand car than a 10 second title in the bank's hand car.

I also went with the Kooks long tubes. Kooks also makes a sweet x-pipe that accepts bolt-in high flow cats, which I went with, or o/r collector connections if you don't want the cats. All that bolted right up to my Borla Stingers, which I wasn't giving up no mater what!
