I have a 2002 mustang gt with a v-2 T-trim. I was wondering if my a/f at 10.6-10.8 and timing at 14 degrees non-intercooled to to much? I using the stock pulley a 3.60 pulley on my t-trim and I am pushing 10lbs at 6000 rpms. I want a intercooler but money is tight right now.. It fells sluggish until I get into the upper rpms.. If any of u have any comment please help. I dont want to blow it right now. thanks

Your a/f is too rich. It should be 11.2-11.5 that is why you are low on power. Your tuner probably did it to keep you safe if you have stock internals.

nah he tuned my car when it was 65 degrees outside and nw its 90 degrees out side. my last a/f was 11.6, but mostly 11.2. way more power. He burnt me a chip using sct. I wonder if i bought a sct flasher or programmer if I can change the setting to get the a/f back to normal?

You would have to have him email you a copy of your file so you could load it on the flash device then, you can only lean it out a max of 6%. I've actually got the same situation, mine is maxed out lean and still reading 10.9-11.2 wot.

Dont do anything yourself with that much done to your car. You say money right now is tight...well if you mess with it yourself and you blow your motor up, you will be paying more than you would be if you were to pay your tuner to do it right. So do it right the first time so you dont mess it up.
