Took the gst to the dyno this weekend

['92eclipsegst]

I was pretty happy with the results. It made 294whp and 270lb-ft of torque untuned. Mods are: sfp exhaust manifold, garrett 50 trim, apexi turbo-back exhaust w/ cat, tial external wastegate, 550cc injectors, walbro 255lph pump, greddy fmic, greddy type s bov, emanage blue, and a southbend clutch. This pull was made at 15psi and the car has not been tuned. What do you guys think of the numbers?
oh and I think the graph is shifted to the right a bit because they should not have revved the car to 7500 rpms.

What kind of gas was this on? Your AFRs are a bit on the lean side, though they richen up as the pull goes on. At around 5300rpm or so that dip might be the effects of some knock, do you have any way to datalog? For 15 psi it's not bad, but it's not great, to be honest. I think that you definitely should invest in some way to run bigger injectors if you can't already (I don't know emanage) and grab some 750cc's, those 550cc injectors cannot support that turbo. All in all I would say its a good start.

Yeah he can go bigger injectors with the e-manage, I'm running 1000's with the E-man, and I think you can even run 1150's.

Not bad, but not great especially on a Dynojet. I'd say larger injectors are a must and to tune out that lean spot. It should start slightly rich and stay consistent the whole way threw. Definably a good start though. Larger injectors, fuel pressure regulator, and more boost!

Thanks for the comments. I like you guys said, my next mods are: injectors afpr, and a datalogger. The mods that are on the car all came with it otherwise I would have never bothered with 550's.
And I forgot to mention that I don't think the a/f ratios on the graph are very accurate. They just stuck a pipe with a sensor in the car's tailpipe to get the ratio. My innovate lm-1 doesn't show any lean condition below 4k rpms but actually shows an a/f ratio of ~11.2 while under load so I definitely need some tuning.
