Well I finally got the car on the dyno and I'm a little dissapointed. Went to Merrillville IN. to a place called MROZ. Really nice dynojet. Dan, the dyno operator, Is a great guy to deal with. The tune was done by Ion Solton. The first pull The spark lead was hooked up to #1 cyl plug wire and had a bad miss and only read 255 hp. Bad coil pack im guessing. Plugs and wires are new. Converting from MPH it was actually 357RWHP and 350RWT. Then we hooked it up to the #3 plug wire and got good pulls from there.
The final numbers were 372RWHP and 360RWT Which seems pretty low. This was done with the mods in sig, minus spray, Stock injectors. stock intake. In the A/F graph it looks like the the fuel was petering out. Pressure was good but was choking at the injectors maybe. Tuner advised bigger injectors. Is this good advise? If so which injectors? I also need a new coil pack obviously and LS6 intake. Any other advise or comments welcome.

I think that LS1 intake is whats really holding you back. Get that taken care of and see how it goes.

A pulley and Intake could add anywhere from 18-25 rwhp, which would put you at 390-397 rwhp. That sounds better. Also, depending on where you dyno, that could be the difference between 397 and 405. Then, depending on who tunes it, someone else might be able to squeeze another 5rwhp out of it. That could put you over 400rwhp.

I think the intake will really be holding you back with a nice cam like that.

Thanks for the posts. I really do need an intake. I sent a guy from this board $250.00 for one and the ******* never sent the intake. This was 4 mos ago.

I don't think you need bigger injectors until you start spraying. I have the same
cam with the mod's and #'s in sig and my injectors were only at @ 91%.

My numbers are in the sig. I would throw up if those were my dyno numbers. You need the intake, crank pulley and you also need a retune. The car will run better being more rich. Go to around 12.5 then after around 4500rpm lean out to around 12.9. How much timing are you running? I would go for around 29-30./
