stock 3.8 pulley, injectors that came with the maggie and a zl1 fuel pump, no module. Duty cycle was @ 95% so in putting in 850's before i put on ported throttle body and 3.6 pulley. Should be 650 ish. Best bang for the bck is the OD cog and zl1 pump-whole nother animal!

What brand and type of dyno? 450 on a mustang dyno is probably ~500rwhp on a dynojet. Don't get caught up on numbers.

The ZL1 pump isn't worth anything without the FPCM to make it work to its full capacity. It's less than $500 to get both.

Thats pretty low boost. Certainly a very safe level of boost for the L99. Most of the L99s I know of running the 2300 are running 8-9 lbs and getting into that 500-550 rwhp range.

I would get a better breathing intake for sure. That right three may add 20 hp. You may also want to repulley just to get boost up a bit more. 5 lbs sounds low for even the stock pulley.

Yeah i am thinking a Rotofab Cai with the adm scoop. Im not sure wether to get a smaller size pulley maybe a 3.6 or get the OD Cog drive. I just put on the 1:1 cog drive so i can here the whine, i dont think i want to take that out. But changing out the pulley would be just as good right? Plus i had 22s while i was on the dyno so i know that hurt my numbers as well. Thanks for your response

If I change out the CAI intake, I don't think that I need to get a retune right? I know if I change out the pulley or the OD cog than I would have to get a retune.

I would retune if i added any more bolt ons to a FI car but thats just me. The shop should retune you for a big discount.

You will need to get it retuned with the new intake

It's a dynojet but I believe since they just moved into a new shop and got a new dyno it's a eddy current loaded version.

Not to cut in on the op post. But why the big difference on the dyno? 50HP is a lot.

Dynos just perform differently. Some are just more conservative on bigger HP builds (Mustang). I ran a 663 on a Mustang & 716 on a Dynojet.

There are a ton of things that can affect the output on the dyno. Temp, humidity, calibration on the dyno, where its setup on the rollers, the break hanging up on the wheel, operator error, the list goes on and on.

Like Kronix said, different dynos read much differently. As long as you are not going lean, I wouldn't worry about the numbers. I put down 622rwhp on one dyno in 108* heat and then did 658rwhp on a 73* day, on a different dyno with no changes being made to the car.

Do you have a copy of the graph? Was it choppy or smooth? What smoothing factor did they use? You could have had wheel spin on the dyno that gave you artificially low numbers too.
