Cobra GT Posted November 23, 2007 Report Share Posted November 23, 2007 Took the car to Justin @ VMP yesterday. The car cooled down about an hour before the baseline run and the then about 40 minutes between pulls. The only modifications on the car for the first run was Corsa axle backs. 446.65 RWHP with 446.38 torque. The last run was with the JLT intake and Justin's tune. 504.09 RWHP with 486.76 torque HER_ASP.pdf HER_ASP.pdf Link to comment Share on other sites More sharing options...

The last run was with the JLT intake and Justin's tune. 504.09 RWHP with 486.76 torque Looking at the dyno chart.... does the stock tune really start off that lean and go rich at the top end?? Wow!

Cobra GT Posted November 25, 2007 Author Report Share Posted November 25, 2007 What octane fuel did you tune to? That's a nice increase. 93 octane. Too bad it was not last week after the cold front came through. Link to comment Share on other sites More sharing options...
Justin00Stang Posted November 25, 2007 Report Share Posted November 25, 2007 Looking at the dyno chart.... does the stock tune really start off that lean and go rich at the top end?? Wow! Yes, in the low RPMs the computer commanded .89 lambda, which is over 13:1 A/F, and then up top the factory maf xfer is off a lot and the cars run rich. I've spent some time coming up with a correct maf xfer for guys still running the stock airbox with a tune. Link to comment Share on other sites More sharing options...
