Which ECM and tune?

I have a 347 in a gen3 camaro. It is all forged, Ported Heads, Ls2 Intake, Stock Injectors, 5400 Stall converter, and 5.13 gears. I do not want to use a MAF! My goal is to run about 10.70 in a 3000 pd car!!! It also has a Powerglide So the Trans controls are not used! What I want to know Is what Sensors do I have to absolutely have to hook up???

O2 Sensors
Cam Sensor
Crank Sensor
TPS sensor
Coolant sensor
Coils
Injectors
These are the sensors I have Now!!!

Now What ECM would everyone recommend, Should I get the gm Reprogrammed, or try an aftermarket??

What about a wiring Harness? Rewire an original, or Custom?

I am open to all options because I have no wiring or ecm yet!!!! Vendors Price me the parts I need in a PM! THanks!!

Thanks for your help!!!

The first thing you need to do is ditch that intake. With a 5400 converter, that thing will be past its peak as soon as you leave the line. You should probably look into bigger injectors too. For the sensors, you left off the IAC and knock sensors and map sensor. As far as ecu and wiring...how much money do you have? A stock wiring harness and ecu will work just fine...lots of high hp cars using them...and they are pretty cheap. Or you could go with BS3, EFI, MOTECH, etc. if you have tons of money. I used stock wiring and ecu when I did the swap in my third gen.

What Intake do you suggest? The Wilkes Stock Eliminator B/SA went 10.23 with Stock intake and Injectors! No Ported heads and in B weight!!! What pound injectors? I am FIne with using a Stock Computer and Wiring! What year do you suggest I get the ECM and Wiring FRom? The engine is 99. Should it be from a t56 car?

If you have the cash, I would go with a fast intake. As for what injectors...we need to know a little bit about the motor first. Well, for your car, it really doesn't matter what year or tranny the ecu and wiring come from. The '01-'02 cars had a better os, but that can be loaded into a '99-'00 ecu. The '01-'02 cars didn't have egr, so that's a few wires you won't have to remove...but if you are removing wires anyway, it really doesn't matter.

Thanks Man You are a Big Help!!!!! The engine is a

347 Iron Block
6.125 Rods
Probe 10.5 to 1 pistons
853 Ported Heads
Titanium Valves Stock Diameter
5/16 Heavy wall pushrods
Stock Rockers
Patriot Spring Package
Ported oil pump
CAmshaft:
Thunder Racing Custom Camshaft
"sTRoker" - 244/248 - .612/.615 - 112 lsa 2400-7500 RPM Power Band. Intended for engines 6.6L (402cid) and up. Lopes hard. Strong mid-range & high RPM power. Requires computer tuning, 4000+ converter on autos, 4.30's or greater depending on transmission. Works very well with nitrous and proper tuning. Due to the fast ramp rate of this camshaft, the use of 1.8 rockers is not recommended. Due to the extreme nature of this camshaft, piston to valve clearance must be verified when using modified cylinder heads.

I guess I planned on shift it at 7200! Let me know what you think!
