John once you have software on laptop you can have your programmer tuning installed and read that with your laptop saving it as a starting base for improving your custom tune.

The nice thing about having the software is you can save several level of tunes and flash them at will while saving the tune you are changing out. You would put stock tune back in after copying the superchips info to laptop as you cannot flash the new altered laptop tune unless the stock tune is in place which would be stored on the superchips tuner. You can also make an extra copy of stock tune in case of a crash so you would not have to take PCM back to dealer to pay to have it put back in.

On the forum members can upload tunes to the forum for members to download and try them if it fits your need. I know there has been a stock tune on the forum a long time incase anyone crashs and does not have stock tune to put back in etc.

I will have 6 to 8 tunes maybe more saved on my computer based on which SC pulley I'm running, methanol inj. or temp range of spark plugs as well as quality of wires used plus if i'm running upgraded coil packs. Say tunes for interstate cruising for traveling, street tune to economize, then power, and full race tune with methanol injection. I'm even looking at seeing if there is a way to run a pulley for ac, water pump, and power steering bypassing the supercharger while on long trips to see if it would help fuel economy. I do not think it would make a difference anyway as the SC only uses a 1/3HP during non boost. Just really thinking outside the box in every way i can all the time. Maybe why i have health problems i use my brain to much on some things that should be left alone. LOL

You would of course have to work in limits of pulley size running and ability to control fuel pressure. It is not critical as fuel sys. is designed to bypass but, not over using it makes it last longer. I did not make the tank pump change out or in line add-on pump since i wanted to go with Keene Bell boost-a-pump system. Bell kit lets you get full use of stock pump which is more than able to provide fuel pressure needed, plus it causes the power source to pump to be leveled out with same voltage all the time (no spikes) which is a big culprit in pump life also constant steady pressure helps with an even better tune as you can count on fuel required being there. I feel i can do extra fine tuning with fuel delivery leaning or riching the engine right during runs with partner making adjustments but, then marked for reference to check computer log to see what happened. I just do not want to over use the fuel pump pushing more up front than needed and those with tank pump change outs would want to stretch the life of the pump more anyway.

Just preventive type stuff. I'm weird like that and drive Dragon nuts some because i try to think of every contingency. I think it is why Dragon and i do such a good job on complete custom builds is because I'm picky in certain areas and Dragon is more so in other areas. I have let him down some on my end not being able to go to the shop all that i want or needed but, Dragon can do it no problem. Dragon is real picky about electronics end and the body customization as well as the paint scheme. He has a great gift of design. I really look more at the power and performance side though he is very very capable there as well. On tuner cars Dragon is really in his element. The shop customizes anything so Dragon on MotorSportsAuthority.com side has to look at anything from rice rockets to old school muscle cars. He does not know it yet but, I think the next project i want for myself is to take a 2000 model Miata and change the engine, drivetrain, and suspension to run a small block 289HP or a little larger motor either old school mechanical power only or hi-tech supercharged or nitrous add-on power. Leaning heavily to old school.

From the sounds of your experience I do not see why you should not go with the HPTUNERS software and laptop after you are familiar with intial setup and playing around with superchips programer. The newest programers i understand have allot of tunability in them now compared to 3 years or so ago. But, starting with a programer tune is the way i recommend anyone to start out. You have a tune that you know you can run around on while you tweak it on your laptop.

Look at forum at HPTUNERS and you will find answers to questions you have not even thought of yet that have been brought up by first timers and the main man himself Keith will be on there moderating and answering questions in real time even. The 3 young men that started this company are great guys and deserve all the success they have had. They had many offers before MSD asked them to do superchips tunes for them but, the guys were being asked to give up to many things in various offers by others. They would not sell out for the sake of the all mighty dollar. Creativity had to be under their control and the deal had to not in anyway have anything to do with what they did with their company. I just hope the success does not ruin them. My sponsorship will be up after this summer but, i had hoped to do the Texas Mile in late Oct. 2007 and set a speed record for SUV's in the open class which is held by basicly a stock Tahoe at 125MPH at end of mile and through the trap. I know i can blow that away. My health issues and Dragon running behind on some of the upgrades he has, i do not know if i can make it since I have allot of tuning to do once i get H2 back in my hands. I had just started to move in the direction i wanted to go which is 16 to 18lbs. of boost which has to be done with caution, so having time doing it is more critical than meeting deadlines. There would be another chance in Feb. of 2008 so maybe i can make it. i had hoped to do the mile trap and earn sponsorship for a while yet more. HPTUNERS has fulfilled their obligations with no complaints by me.

John just read more on HPTUNERS forum and you will see it is not hard. Buy yourself the newest G-Tech Pro unit that will allow you to check HP at the wheels as well as torque. It does 0 to 60, 1/4 mile times, 1/8 mile times and with the Pro unit it will have software so that you can get print outs that will look like dyno sheets. There are few all wheel dynos that are large enough to hold a H2. Go to the Pro website and read up on it. They have a great tech support as well as customer service.
