Adam at ST Motorsports who knows his sheet told me that he will tune my car for the 18# pully and I can drop to the 14 #er with no tune change, The computer in the car will adjust. This is with the KB 2.6 though.

Personally, you've spent how many thousands of dollars on your SC and your car... you really wanna cheap out now and not get a tune that could well save your motor?

That guy is a moron! Yes you have to retune with a pulley swap on the Saleen. I would order the 3" pulley from Brenspeed

You DO NOT need to retune if you go from the 3.4 to 3.2 but will if you go to the 3.0 pulley. With brenspeeds tune atleast. I am more then happy with the 3.2 pulley there was a huge difference noticed just by swapping the 3.4 with the 3.2 pulley.

If you are only dropping one pulley size you should not need to retune the car.

actually a tune 4 lets say a 3.6 pulley can also be used 1 pulley size smaller ;ie 3.4 pulley and so on. this comes from 3 tuners, jim jr at jdm, brent at brenspeed and justin at vmp tuning...so for going just 1 pulley size smaller its not needed...if that is the only mod u do...however would I still spend the couple bucks for my own peace of mind..u bet I would...don't save money with a tune when using s/c...but again that's my opinion..

every car is different, but it seems that most don't need a retune when dropping one pulley size, and yes 3.4 is the next one down from a 3.6. I personally would retune after dropping pulley sizes just to make sure I am getting as much HP as possible.

I should say brent from brenspeed sent me a stage 2 tune originally for 3.6 pulleybrentthen sent me a stage 3 tune for the 3.4 pully brent said they do not retune for the 3.2 pulley but they do for the 3.0
It really depends on how deep your pockets go andif you feel the need to custome tune after each pulley. If i had 500 each time to retune I would be more then happy to retune everytime I changed something. I let the dyno speak for itself.

I have heard whipple says that their tune for the HO is good for 10psi tune can be used with 8psi or 12psi.
Just food for thought

No way would I put a 3.0 pulley on a stock motor.
