Is the pro version worth the extra money. will version 2.1.18 tune my 08 sierra?

 

Absolutly yes!!

 

Definately! Logging with a wideband directly through the interface box is more accurate than trying to go through the a/c or egr signal wire, too many problems with ground offset issues...... and the stand alone data logging is a nice feature to have as well.

 

added a question in my first post

 

2.1.18 probably won't, however there is a newer software update 2.22(which is free) that should be able to tune it without much issue.

 

I've Got a '09 Chevy Silverado Ext cab 5.3 V8 and I was told HP Tuning was a great tuner but I can't find any place here in Houston that Tunes with HP Tuner. Does anyone know of a place or someone who is familiar with HP Tuning and can tune my truck?

 

You will need 2.22 in order to tune the 07+ trucks.

 

HP Tuners is the software and hardware that allows you to custom tune your vehicle. if you are looking for a person to tune your vehicle that uses HP Tuners, in the Houston area Wheatley (see post above this one) can help you out.
