No meth right now, I took that out for the time being.
I am at the limit of the stock fuel delivery setup. Tony tried to put in more fuel and boost above where we are right now and it just started to lean out at high rpm. Right now I am at ~11.7:1 just before rev limit with the setup I have.
I'm looking into fuel system upgrades but for now this is plenty of power!
I think for a larger dyno number we are going to try and run it with C-16 and more timing. I might also hook my meth kit back up.

What size injectors are you running?
I ask because I was doing my first street tuning runs yesterday using the boost controller and at ~13psi I was holding low 11:1 AFRs in the upper rpms. I have 650cc DW injectors and just the Walbro 255hp in the tank. Now I was seeing 94% DC peak, but I think I can get a little more out of it If I lean it to mid 11:1s. I may push up to 14.5 psi,but thats all I want any way for now. Do you have a way to log fuel pressure?
Also, what is your conservative timing in the 13psi load coloum? Im tuning the AFR using 12 degrees advance and getting what I think is engine noise showing up as 1 knock count on several spots on the data log. I get a 5 count on the 3-4 shift Whats your knock sensitivity set too also?
Cant wait to see your race gas numbers!

The only company left down here for the Z/G family is Relentless Autosports.

What about GTM and Precision Z and Technosquare?...
I'm certain there are others that I am not aware of or haven’t dealt with...
Where do you get your stats?... What all did you have done?...

Edit: after reading my other post again, it definately came out wrong. It's funny I re-wrote it a few times trying not to sound like an ass, yet I did anyway .
