So I've been trying to get this 87 Turbo T tuned in and not havin the best of luck. Car has a stock turbo @ 17PSI right now, stock ic with dutt neck, 3in dp with turbonetics external wastegate/boost controller, cold air intake, 42lb injectors, adj regulator, egr deleted, jay carter chip and walboro pump. Everything else as far as I know is stock. So I put the direct scan on it today and started seeing where the car is at (as it seems to lay down around 50ish mph and doesnt seem to wanna go anywhere. 1st wot pull recorded 39 counts of knock - with it pulling about 5.0* timing at 52mph 
So I checked fuel pressure and it was at 38psi line off. Simple enough adjusted it to 42psi line off and started off again. 16 counts of knock later, I pull over and adjust it to 45psi line off. 9 counts of knock... >_< Adjusted it to 45psi line ON and tried again. 3 counts of knock still....I didnt think that a stock turbo needed so much fuel! 0_O BLMs are all over the place - it says its at 119 @ wot, but then why is there still knock there? ??? -Ben
