I have a laptop and the cables for connection. In goin to put a single plane manifold and put my injectors in it. I then putting a 1200 cfm TB with a 4150 flange on it. I have to reprogram my ecu because im losing the 58mm TB and LT1 manifold and MAF. Im also deleting my EGR and AIR and need to reprogram ecu for this. I need to delete them out with some sort of program. Will this increase horsepower and by how much?
Please Help!

 

You're putting "a 1200cfm" what on it - throttle body? If you need a single plane intake and a 1,200CFM throttle body, you must have some humungous heads and a big cam. Then you apear to be converting from MAF to speed-density. That setup would need to be "tuned", or it won't even run. You could do it with LT1_Edit, or with TunerCat software.

Can tunercat delete things out my ecu like MAF,AIR,EGR,etc. And can it give my motor my fuel and adjust idle. How much HP will the new intake setup give me

 

You "delete" the MAF by switching the stock PCM (using tuning software) from MAF to speed-density. You can eliminate the diagnostics for AIR and EGR with tuning software. You can alter A/F ratio in power enrichment (PE) mode for general power tuning, and tweek VE to alter the fuel in specific RPM ranges. You can change the spark timing and adjust idle speed. I don't know the details, because I don't have a stock PCM in my car (I have an aftermarket ECU) and I never used TunerCat.

What are you putting the single plane intake and 1,200CFM TB on? If you put it on a stock engine, you will not gain much of anything. If you put it on an engine capable of making more than 500 flywheelHP, it will definitely help it breathe better and make more HP.

 

It will make 500HP when sprayed.

 

You don't need a single plane intake, or a 1,200CFM throttle body to make 500HP on motor, let alone on nitrous. I'm making 800HP with a ported LT4 intake and a 58mm TB. Engine dyno testing shows I could have made the same HP with a 52mm TB. I've seen a 383 LT1 w/ Vortech S/C make 1,125HP on an LT4 intake and a 58mm TB. You appear to have money to burn if you are investing in a single plane and a huge throttle body to make 500HP.

 

What is done to your motor

 

You could probably still run a MAF if you used a bonnet and some pipe. It would probably be a tab more drivable that way. Just a thought.

 

I laid down 506 rwhp / 600 rwtq through completely stock heads and intake on a 175 shot. You don't need a single plane.

 

what do you plan on running for a motor? last time i checked a typical single plane was usually good for power up to 8500 rpm's which you will not even come close to touching with a stock lt1, probably not even a fairly heavily modded one. 1200 cfm is a hole hell of a lot of air. maybe throttle bodies are way different than carbs, but i know that my buddys 383 that put him deep into the 10's(on motor) only had a holley 850 on it. unless you are building some sort of insane radical motor that you are not telling us about, i think your eyes are bigger than your grip on reality. i am not trying to be a d*ck but realize that a huge throttle body and a super high performance intake do not make power on their own, they need to be complimented by other parts that are capable of the same things. heads, cam, proper compression etc. by the time you get to that point, there is no "how much hp will this mod give me" your setup will probably be all custum built and unique and whoever makes your cam will make you swear an oath of secrecasy about the specs, so nobody can really even make even a logical assumption. except maybe a dynojet!!!

my $.02 take it or leave it

 

In a sense they are. You're not introducing fuel through the throttle body (in this case), so it's just an air valve. Even if you open the blades all the way, the motor is only going to pull the amount of air it needs. If it only pulls 800 CFM, then the throttlebody will only flow 800 CFM even though it's capable of 1200.
