If I have the Perf 93 cai tune installed and then want to modify the stock tune , say to turn of the mds, will that overwrite the perf tune ?
Thanx in advance.

I don't know about your problem, I updated mine last to vr20 I changed the shift points, firmness reset the TCM & bumped the redline to 6200 and boy it's a new car and it's BAD. I put it to the floor from a dead stop and roasted the tires when all of a sudden that f*cker snapped into second and ...

Thanx Mike!! I am glad I don't need an update, I got over 50+ hp from the cai 91oct tune and thats with wheelspin out the a**!! I hope this 93 tune gives a nicer bump in hp gains!. Keep up the good work.
Thanx again guys

I have version V.8r14, the selections listed under DiabloTunes are;
performance, perf cai, perf 91 oct, perf cai 91 oct, modify stoc tune & original backup. Does that mean the perf cai tune is for 93 octane???

I only have Perf 91 oct cai tune?!?!?!?!? Where is the Perf 93 octane tune?

okaly-dokaly i'm gonna go plug it in again, maybe i missed it somehow? thank you

How do I get the CAI 93 octane tune for the 2007 hemi R/T? They only sell 87,89 & 93 octane where I am, not 91!!!
