i have one option left. it's a bit extreme, but with some tweeking here and there it will work fine.

p.s. use your timing, and pe tables. mine will cause issues with your car

 

I dont trust myself messing with those types of tables...still kind of a newbie with the hptuners.

 

just copy your high octane table. and your PE table to the map. then go out and tune from there

 

Well I put a new Supercharger gasket on and cleaned the TB.....seems to have taken care of the issue. But i will drive it around for a few days just to make sure.

 

Cleaning your MAF with MAF cleaner from auto zone or something. Apparently they are super sensitive, I clean my TB and the MAF and it doesnt do it anymore.

 

mine surges now. cleanin the maf this weekend. i have found that if you pop the car in neutral and release the clutch. it doesn't do anything stupid and idles down like normal

 

if you clean the TB... you should be fine... our cars tend to build up alot of grim in the TB... so check that... and clean it...

 

I got a shitty tune on my car cleaning the MAF cleared the idle issue right up.

 

Although im late, I would clean the MAF also, AKA mass air flow sensor. If you are running an oiled filter oil may be getting on the wires giving false readings to the computer. Its very important to keep it clean, I clean mine every oil change with a oiled air filter.
