2010 GT factory tune vs. Bama 93R dyno results

Hey guys, I mentioned this a while back but sorry for the delay in posting . . .

Here is a dynojet graph of my 2010 GT (manual trans, 4th gear, 3.73 rear) -- blue line is the factory tune ; red line is Bama 93R. Of course I had 93 octane gas in the tank; the 2010 factory tune has the adaptive spark timing so it should take advantage of the 93. Everything else was the same, as close as I could get it. We did let the engine cool down a little between runs; of course we could not control everything to make it exactly the same; the two runs were within an hour of each other with nothing changed except the tune.

Max numbers went up by about 5 HP and 7 TQ for the Bama tune versus factory.

You can see in the curve that the Bama tune is above the Factory throughout the RPM range; looks like about 12 FT-LB improvement in the 4,000 RPM neighborhood.

Mods were:

- Roush CAI (same MAF tube diameter as stock, no tune required)

- shaftmasters aluminum driveshaft (does not change engine output, but supposedly reduces drive train losses)

- Steeda underdrive pulleys (reduces losses to alternator, air conditioning, water pump)

- FRPP FR-500-S mufflers (not really a performance mod, but listed for completeness)
