I am hoping there have been more powerchip experiences for the M271 engine. Do you guys have any? If you need to send me your opinions via top secret methods, PM me the message, or PM me your email addy please.

speed innovations ecu tune...

I love my Speed Innovations ECU tune

I'm gonna +3 this one... I have an SI tune (only people to develop one on top of the KBOX as well).

when you say "on top of the kbox"... do you mean that its effect is super imposed on the kleeman kit which includes the k-box?

The K-box is a piggy back unit with limitations - software tinkering/engineering within the DME equates to a more precise tune. SI improved what the K-BOX cannot. One example, have you ever seen a piggy-back unit remove the V-MAX speed limiter?

How can this value essentially be changed by a hot and ground wire? Shift points? I still have my KBOX, but would've never been satisfied with it alone.

How much is the SI ECU Tune... I was going to order the Kleeman Kit and now that this thread is here I may do the SI tune... I have also been talking with ASP and they said they can research making a pulley kit for the M271 if I bring in a ECU Tune such as the K-Box... I was thinking about buying the Kleeman Kit and taking the Car to them and see if the can get more out of the SC then the kleeman...

What are the price for powerchips?
