Cool,let me know some numbers when you get them,very curious

I'm still on the can tune so I don't expect very good numbers ..... However the pulley change made my data logs look better

Ecutek and seb at specialty have been amazing so far man,amazing customer service

Jinxx · 04-18-2016, 12:34 PM

soooo I dynode the car today ...... car was maxing injectors out so I need to upgrade...unless I have room to increase the fuel with the 650cc ... as it was it made 480whp and 350tq @7200 rpms but started leaning out around 6500 rpms and at 7200 was around 12.8 afr.... I don't know how to post a pic or vid yet ill post it when I figure it out

Jinxx · 04-18-2016, 02:32 PM

first dyno run can tune .......the 480whp is a 5th gear pull...the 390whp is a fourth gear pull [ATTACH]

I didn't get the psi off the 4th gear pull but I got it for the 5th gear .. 12.3 lbs at 7200

What kind of dyno is it?you should be able to hit 500whp on 650 injectors on 12lbs of boost,do you think the uprev is holding you back?where's your wideband o2 mounted on pipe

Jinxx · 04-18-2016, 10:32 PM

It's a dynojet .... Not sure if I have any adjustment left in the tune ... I never installed the voltage regulator for the fuel system Seb says at this point voltage regulator won't help and I could verify the fuel pressure .. If it's a pressure drop tunning would help if pressure doesn't drop then I could tune it but recommends me going to return fuel system ..... Not sure how I wanna go about it yet ... Prolly should just do the return kit

I'd call cjm,I've had great dealings with them

I talked to him today ... I think the return will the best route to take .... Always something .... But still I can't complain too much

Are you going with ecutek?

Jinxx · 04-23-2016, 09:45 PM

No not going with ecutek ..... I'll hold out for a while for up rev to update

tiller · 04-24-2016, 12:12 PM

We're you able to see where exactly your fueling issues on the dyno were happening?like rpm wise?do you have an FPR gauge on your rail?

Jinxx · 04-24-2016, 02:41 PM

I don't have a fuel pressure gauge ...and I think it would have been fine with the 92mm pulley and prolly a little rich .....but after changing to the 85mm pulley the boost comes on much sooner and running 40-50% more boost ..requiring more fuel ..once I get the return fuel system to be able to increase the fuel pressure as boost increases it should be good...I would think the 92mm would have ran around 450ish whp.....

Stock fuel pressure is 52 ...as boost increases it drops soooo with 8lbs pulley fuel pressure would be 44lbs which would support the boost ...with the 12lbs pulley pressure would be around 40lbs and not enough for the boost .....no real way to increase it without the return system
