Does the Mass Sensor --> computer not correct for the lean condition or are you just that much out of the tables to get a correction? That sounds odd to me but I don't mess with forced induction cars. Will you have to get a custom tune programmed in? Running lean is a bit scary, especially in a nitrous, s/c, or turbo car.
I think the only solution at this point is a physical one - the injectors that Jose & Jesse have. With the new injectors, I think that will drop A/F ratios and will allow playing around with the timing curves to extract more power.

We think the injector is maxed out. I had Jose and Jesse try to increase injector duty cycle but the dyno still showed that we were running lean and the HP graph shows that I'm pulling back on timing. Even on my G-Tech runs, the HP graph really gets ragged at peak HP on my 0-60 run. That is telling me that the computer is pulling back timing at peak boost.

Hey Carlos, YES - I was going to go, either with/without a sign-up. I actually really wanted to meet you since Drex talks about you every other phone call haha...unfortunately have to take care of some 'other' things. Good stuff for us.

LOL - I'm guessing that with the ported supercharger, Ed's gonna need those injectors first. But I won't be far behind - I'm kind-of thinking of doing the same thing. I really have to take a look at getting a throttle body to Jose and Jesse for porting too.
Y'know, all these mods are depleting my "finish my Mustang SVO" fund. I'm sure my wife would like to have my Mustang drive in and out of the garage sometime before my 5 month old son grows up and moves out of the house.
Hmmm... belt squeal? You're not putting any more stress on that belt than was there before - in fact, I'd say you're putting less stress since the supercharger is more efficient now and requires less power to crank out the boost. It could be that the belt has stretched to its limit? Or maybe a new tensioner? I have to take a look at the C230's tensioner. I know one simple trick for Fords is to notch the belt tensioner so you can advance the spring a little to increase belt tension.

Yeah, I can see that. I think people don't want to step up to the plate because they want to see what the actual returns are (hp, etc.) and then vascillate between mods. To be honest, $200 for C32 swaybars or $250 for a throttle body? Both are good and can be argued either way. That's why I tip my hat to innovators such as yourself, emrliquidlife, mig888 and buellwinkle for stepping beyond the "knowns" and taking on the unknowns.

As for the decision between the sways and the throttle body...hmmm...I can see the dilemma. Power is so much more fun when you can use it in the turns...LOL. Can you say, "my esp is going nuts!..."

Drex, thanks for the kudos. I think we can all benefit from the development of mods for our cars. Nice to have performance options, y'know?
Emrliquidlife: I haven't had my injectors reworked yet. RC Engineering is a good place for cleaning and flow-matching injectors, but I don't know if they carry the Siemens injectors our cars use. Jose and Jesse found a source, so I'm inclined to just go with what they've come up with since it looks like it's working well in Drexappeal's car. BTW Drex - that video that Flipachu put on youtube of your car was pretty cool.

Seriously, I've begun to wonder what the diamter of our ring gear is. I know that a Quaife LSD is available for the C32, but not for our cars because our differential is smaller. I'm wondering if there's a really close equivalent that we can use? Maybe a LSD with nearly identical inside diamter for the ring gear that only needs the mounting bolt holes drilled and tapped? I know it's more than that - input splines need to be the same, etc. But it's got me thinking...

Let's just say the car is running like a completely different car, but just as smooth as when it was completely stock. No error messages, smooth idol (except maybe when first starting the car from cold start).
As for the video, that was when the headers were first bolted on. They were so much louder then because they were still breaking in. Now, you can only hear them on acceleration (and it is still super subtle).
I'll give you all more updates tomorrow.
