Just installed a 2.3L VMP SC with a 2.8 pulley size, good for 18PSI .I received a mail order tune for 93 pump gas. Finally put it on a mobile dyno and the results were not too impressive. Max HP 564, Max torque 480. I was hoping for more torque.
Dyno results after new SC install

Don't get hung up on dyno numbers bud,its the track that don't lie
What dyno was this ?

Not too bad .... but with a mail ordered tune you really don't know what you have!! I'd personally try to get your car to a real tuner!!
Good luck .... there's more TVS power there!

I agree with Tim. You really don't want a mail order tune. Have your car dyno tuned for an optimum tune. There's definitely a lot more on the table.
Your mail order tune is leaving tons of power on the table. If you cant find a reputable tuner near you, remote tuning is always an option. Based on your current numbers id say you car has a lot left in it. Goodluck.
The shape of that torque curve is a dead giveaway you've got some tune problems. I'm also assuming you disconnected the boost dump solenoid in favor of a direct boost hookup to the boost bypass/FRPS line. Usually these things have a nearly flat torque curve out to 5500 RPM or more.
For a mail order tune, not too bad. Problem with mail order tunes are they are basically a slightly agressive "base map" if you will to go with your mods. A real tune will probably get you another 20+hp and tq because everything can be adjusted to perfection
A mobile Dyno Jet 224 was used. Granted the outside temp during the run was 100 degrees, I expected slightly higher numbers. I have a wideband so I datalogged several times with SCT software. Justin at VMP sent me several tune revisions. I'll be taking a road trip to HPP racing in Dallas soon to sort things out.
Yes it was not a mail order tune per say, even though I received it through e-mail. It was a remote session with VMP.I should of asked for a more aggressive tune than a 93 pump gas tune. Ever since my upgrade I have been using torco to increase my octane to 100 as a extra measure of security anyways. Here in west Texas triple digit weather all summer is common. The only changes I made since the remote tuning session were new Borla cat back system and switched from TR6 to BR7EF spark plugs gapped at .026".
