Anyone in Indy comfortable (haha) with tuning a Hydra 2.5?
I'm having a hell of a time getting this thing tuned. I don't have interest or time in learning to tune it myself at this point in time, and the people that i know of around here that have Hydra experience don't seem to be interested in making money.
So.
Anyone?
Current tune is bordering on undriveable.

I don't even know if it has auto tune.
Driveability issues:
Idle surges like crazy
Stalls at 50% of stops
Hard starting/long cranking
Continues to "cruise" when foot taken off gas for a second or two
Extreme rev hang
Power issues: Slow as ***** for a car that dyno'd 245whp on FM's dyno. Feels faster at 75% throttle than 100% throttle. Falls on its face after 6000rpms. (Feels like it hits a timing wall.)
I test drove RX8s yesterday if that tells you anything.

ok. I hear ya. It really takes maybe 5 minutes to adjust your settings.
idle surges + stalls = settings>ISC>(lower by 10 press enter) add or subtract till bliping the throttle doesnt stall the car.
Hard start..... wait 2 seconds after turning your key to the on position before cranking. Not like stock but close enough.
Continued cruise...... Settings>Setup>check enable fuel cut on decel. then.... Select>Control 3> fuel cut limit>> make it 1600 ish down to 0deg C........
And i could continue to explain the auto tune. Really not a big deal.

I do that with the hard start. Still usually won't start on the first try. If it does, it'll stall.
I'd really rather just pay someone to tune it. I have no real interest in tuning this thing or messing with it myself. I wasn't kidding when i said i don't even know how to get into the ECU. I don't know what software it's running, what build of 2.5 tuning software i need, no idea how to open or modify maps, save maps, nothing. Never touched this, never planned on it.
That's not to say i don't appreciate the help, though. If i'm bored when i have time to mess with it finally say.... next summer, i'll take a look at it if i haven't found someone to tune it by then. Or if i haven't just sold it.
