I have recently purchased a 98 mustang gt 4.6, it has had some mods and has a chip and tune, I have read alot about rev hang and people making a new gasket to fix it, is there a actual part to fix this problem or maybe something that can be added to the tune instead of making my own gasket?

Yes. First, be absolutely sure there are no vacuum leaks. The engine and lines are approaching 20 years old. For the tune, an increase in dashpot decay rate will make RPMs go down faster.

I have the Bama sct sfx3 I believe programmer, Is there a decently priced place around here in St Louis that will create a new tune for me, it has 3 tunes saved on it but I dont really know anything about them because the previous owner had them made

Can I just have my tune updated with the dashpot decat adjustment or do I need a complete new tune, are there any places around that I can get a tune at a decent price, I have the bama programmer already
