Default Tuning Issues

Intro: Have and 03 gt 5spd. Full exhaust with no cats. C&L intake with what measures to be an 88mm maf. But still the stock maf sensor. If that makes sense. Has an SCT xcal3 tuner with 'custom' tunes from american muscle.

Issue is: i have pulled 10 degrees of timing from 0-2k and 5 degrees from 2-4k. And still at speeds lower than 80, if i hit a decent grade i will get some valve rattle. I believe tha max the tuner will let me take out is 14 degrees.

Questions are: Should i really be having to cut out this much timing? Had the car for six months and have slowly been trying to take out more timing and see if it helps on my trips on the interstate. 2ndly there are options for egr and rear o2s to be turned off. What would that be telling the computer and should i turn them off?

I have the same problem.

The 87 street tune they gave me works great, if I use 93....

I can only imagine what kind of gas my 93 Race tune REALLY needs

I had the same issue when I ran BAMA tunes. The rattle is detonation.

Solution? Stop running those ****ty tunes. BAMA is the worst tuner out there IMO. Get a VMP or Lund tune and you'll be set.

I would be surprised if your Bama tune was having detonation issues with the parameters that they set. Though along if you already pulled 10 degrees out. It sounds like there may be something else going on here as well. Have you tried returning the car to stock and seeing if the issues follows?

Give the Bama team a call and they can gladly look into this for you and see exactly what's going on. They'll datalog with you and make sure this is taken care of! Our Bama Performance tuning specialists are here in the building Monday-Friday from 9AM-5:30PM EST and Saturday 9AM-5:30PM EST. You can hit them up directly at 888.226.9764 and they'll get you squared away!

When I first got my tunes they were detonating like crazy. I called sent in a data log and they all still ping. The only tune that works is the 87 tune, if I use 93.
As far as I can see I spent over 400$ for something that can only read engine codes

Have the tunes always done this? Was the tune written with the C&L in mind? Stupid question but sometimes people don't think about it. What octane is the tank? Has it been raining hard in your area or have you recently washed the car (before the problems started). Water in the fuel could cause issues.

During the summer I have to pull 2-3 degrees at the 2-4K RPM because its so hot here but that's it. With a Dyno run it would be no different if I had a tune written any other time of the year vs the summer I would need to pull some timing anyways.

I'm sorry to hear that, Evan! This sounds like a crappy experience. You shouldn't be having pinging issues. Have you contacted the Bama team and let them know that you're still having issues?

I'm confident they can get this right for you!
