After doing some reasearch, I found that you dont have to get the Professional suite ($649), and 8 credits are included when you purchase the Standard Suite.

Info pulled from http://www.hptuners.com/order.php

The base cost is $500 and you have to pay another $150 if you want the analog inputs..........and then there are the points. When those run out you have to buy more if you want to continue tuning.

The DHP unit includes 4 analog inputs and is unlimited, .....so no points to purchase forever.
I need the analog inputs for my fuel pressure and wideband O2 sensors.

so DHP is much cheaper for a weekend tuner like most of us and when you say 3800 from 97 to 03 does thant include the L36

yes it includes L36.

That Should also reflect that you can tune the '96 SE too.

DHP Tuner for 3 months now, i have no regrets

Paul i have to ask.....have you ever used BOTH the HPTand the DHP side by side to comapre the features???

because it seems that you dont actually know the differences, and are just looking at the costs associated with the products

No and Yes.

I've used both the DHP and the HPT. No doubt the HPT is a more professional software package, it'* very stable, has a great scanner and many built in tools. On the other hand, the DHP can do far more than the HPT if you consider the 'plugins' but it'* a lot more touchy to use.

Customer support is almost non-existent for DHP and the major selling point, the DHP forum has slowed a great deal over the past year but still contains a wealth of info specifically for the 3800. On the otherhand, there is no migration path beyond the current lineup for DHP but the HPT supports a wide variety of vehicles.

Either way it will entail lots of reading on your part to come up to speed on many tuning aspects but it'* quite rewarding once you get results.

Cheers,
