Finished tuning bone stock SR w/ GT25R. Stock exhaust elbow / manifold, cams, intake... Just a GT25R .86 ar and a power FC for mods. Needs cams so bad. 18psi, pump gas.. very not bad. This is about as much as any bone stock SR on this turbo will do at this boost.

Nice tuning guys! now TURN THAT BOOST DOWN!!

 

that's awesome power for the amount of mods!
was that on pump gas?? 18psi is quite a bit for a streetable/reliable engine, so either run lower boost on street on 93oct, or get some fuel system support.
That SR must fly!:o

 

Now thats what I wanted to see ...I am trying to shoot for the same setup, but Im going via .64 for better drivablitly. I also are going to upgrade the head and a few others but thats impressive.

Also, Martin...who tuned this vehicle you or XAT?

 

I did this tune in about 3-4 hours on the XAT dyno.

btw.. that was 93 oct / 740cc injectors.. sorry forgot to post that up

Martin, how you feel about tuning the FC vs an actual stock SR Rom tune? I've never ventured into the PFC, but its starting to look like an option vs a Rom tune. Though I know both are good either way you go, cost and easy of tuning are factors Im looking for. And of course it helps that my tuner(whoever they should be)is comfortable with tuning my vehicle initially and once I decide to change/upgrade. I was looking for abour 25-50 more whp but so far its look pretty good.

 

cams will open the car up LOTS.

 

who though

 

Very nice numbers and more so powerband. Any sheets with SAE smoothing set at 1?
