2004 LS1 GTO

I bought some things and am close to getting started on it.

I got a Maggie, heads, cam, and headers.

Also have meth and nitrous, but won't fuss with that until the car drives again.

My question. Will this thing start and run using the Magnuson program at the end of the build?

Here are specifics.

LS1 heads CNC ported by LPE. 2.02I/1.57X, CC 921 springs

Cam: LPE GT2-3 hydraulic roller "blower" cam. .573"I/.580"X lift and 207I/220 X duration with a 118.5 LSA

Stock drive on the maggie (112H model)

1.875/3.0 Kooks headers running to cats and a Borla

Walbro 255lph fuel pump w/ Ken Bell Boost a Pump

ATI dampener

MSD coil packs and wires.

I think it will start pretty easily with the stock tune. What are you doing about injectors? That's about the only thing I can see that would cause start up problems.

I am not too sure about the maggie but I remember a few months back reading about a miggie build in a 408 I think. It ran like crap and the guy had hell of a time tuning it. I am not saying this will happen too you but jsut make sure prior for tuning arrangements if you need to drive or tow it to a tuner.
