Here at STS we ran 5psi with the stock injectors on a bone stock car and put down 416rwhp. The stock injectors were probably running a little lean compared to your 43# injectors.
Remember Methanol displaces 2 psi and seems to be perform best after 7.5 psi. Essentially at 6.5 psi you were pushing as much air as at 4.5 PSI and with much richer settings. You still saw a gain to 420.2 rwhp because of the cooling effect. We usually run 8 psi with the methanol, using an EBC that switches from 5 psi to 8 psi while also arming the Methanol. With 8 psi and methanol we usually ran around 490-500 rwhp.
Next time why don’t you try running 8 psi and the methanol. Also make sure to check the following:
You should be running with the M10 nozzle (not the M15). Make sure your pump is the smaller pump with the 4.5" body(metal part) and not the 5.5" body. Your methanol mix should be between 50/50 and straight methanol.
We'll talk more later.
Visszont!

Thanks for any info you can donate.

bradyb is right. The Methanol should be used at higher boost levels. We only tried the Methanol to see how well it cooled off the intake temps. We did have the M15 nozzle in and did not have the M10 nozzle with us. Next time we go back we'll have the boost set between 8-9 # of boost. We also had a problem with the boost controller and it was getting a little late to mess around with it. I'll try to get the dyno graph up tonight.*** I'm sorry but I forgot to mention that we did add a walbro intake pump to this car to keep it safe. I'm not sure if I would risk 400+ rwhp on a stock pump on a forced induction car. It's cheaper to do the pump then buy a new motor.***

We still have a lot of guys running on the stock fuel system with out problems but thats at 5psi and when they do run 8psi it's on the methanol. STS doesn't sponser LS1Tech but if you guys have questions and you're in the NE call me.

Sorry, I did not mean to sound condescending. I am sure you know what you are doing. I did not want someone else to try this without having all the details. Keep us informed of your progress.

Yeah, I actually lost 2psi aprox. after the addition of the IC. Normallyyou wouldn't notice it I assume on a turbo car due to the waste gate making adjustments but on my kit the wastegate is BEFORE the IC so it doesn't know any better. before the IC I would see 6psi constant and after the IC with no other changes I could only get about 4psi, maybe 4.5psi best (not counting shift spikes). Hawk179 saw the exact same effect on his STS kit with the same IC on his Firehawk so I feel pretty confident that it is about a 1.5-2psi drop through the IC.
I am gonna try and retune this weekend and start using the methanol too. I'll definately let you know what I find.
I'm sure we'll have great success next time on the dyno. We'll have more time to play around with the boost,methanol,and timing. I will keep everyone up to date on our progress. 
Ok guys, I just got a call from my dyno guy and my car is finished. He fixed the timing problem I was having but now my 255 fuel pump has ran out of steam. Here is what my car did at 5.5 pounds of boost. The dyno pull started at 2400 rpms and it hit 400 rwtq at only 2700 rpms, it hit 467 rwtq at 3600 rpms and stayed there until 5250 when it started dropping off. He managed to get 498 rwhp at 6000 rpms and he said he could probably do better through the whole range if I put an inline fuel pump on. Another thing that I love about this kit is that whith the upgraded turbo (t67 instead of t60) my IAT's were only 125 degrees with no meth injection or intercooler. I am going to pick the car up tomorrow and if i can figure out how to post the dyno graph I will post it right away. I can't wait.

Verdad Gallardo Do you have a fuel pressure gauge hooked up on the car? Was your fuel pressure dropping at the higher rpms? Are you seeing any knock?If your fuel pressure is maintained and not dropping;then it's the tune.I've used 255lph pumps at 550rwhp horsepower cars before without a problem.

Do you know what fuel pressure you started and ended with during the dyno? If you had no knock then you had enough fuel. I'll wait for your dyno graph to see you a/f ratios. I'll try to get mine up tonight.
