When I take my truck to the track, my street tune and race tune are running the same times. I'm not sure if it's my tune or if it's something simple. It's an SCT Excalibur 2 and I have it tuned through PSI and it doesn't seem to be taking the race tune. Am I doing something wrong or is there something wrong with the tuner or is something wrong with a fuse?

I have a 4 lb pulley, cold intake, magna flow exhaust... HELP?!?!?!

If you tried running in this heat, you wont see much difference. A Race tune is usually only used when your using race gas (101 Octane or higher). If the race tune was meant for race gas, do not use the race tune without the race gas. If the "Race Tune" was not set up for higher octane gas, then there should not be much difference in the tunes., i.e. don't really need a separate tune. Most importatant with a modified L, is to have a warm tune and a cold tune.

Does the tuner screen say communication failure or error message or tune complete? There will not be much ET difference in summer street apps.

Then the SCT is working fine. Most race tunes are little different than the street tune. You will have to take that up with your tuner. They could have mistakenly loaded the same tune to both slots. etc etc

I raise the sift pressure on my race tunes so people feel the difference.
