Those Who Have Used The Svo Extender...update!!!

I'm sorry but there isn't much experience with those boxes anymore. I never ran one, but I had at least 2 people I knew who used them in the late 90s to run EFI Renegade. Back then the only ecm mod you were allowed to run was that specific SVO box; you couldn't run a chip. It was kind of a weird rule. I really don't remember the specifics on how it affected the tune as far as timing.

I'm finding it kind of hard to believe that you have to rev your car that high to get peak power out of it. Have you had it on the dyno yet to determine the peak power rpm? Your ET and mph is excellent for a stock iron head car, so I don't want to question your assessment of the shift point too much.

If you are looking for a tune for your car, and don't want to drop the cash on a dyno tune, or can't find anyone qualified to do it, I can sympathize, because I'm in the same boat right now with the Cobra. There aren't too many people who are really experienced with OBD1 tuning anymore. I spent half a day on the phone yesterday, and either couldn't find anyone who knew what they were talking about, or wanted the car physically on the dyno. The art of tuning a car with a Pro-M MAF is almost gone. I was amazed at how many people said they didn't know how to work with a Pro-M/PMAS signal curve and insisted that we put a Lightning MAF with stock electronics in the car. The Lightning MAF just isn't a very good MAF. When I called Steeda in Lauderdale, they said they have to have someone drive 250 miles in from Orlando to tune on the rare occasion they had an OBD1 car in. I actually ended back up with the same tuner I used 15 years ago to tune my car. He was the only one still qualified to do it, and willing to mail me the chip without seeing the car. Bamatunes was the worst by far. They wanted me to start the car without a tune and tell them how it idled over the phone. I don't have time for that nonsense. 15 years ago I got a tune done by these guys and mailed to me. It runs flawlessly. I have had 2 stroker engines and driven almost 100,000 miles on one chip.

They now use SCT hardware which is pretty much what everyone uses now. That means if you ever have the desire to get the car retuned on the dyno they can just adjust the chip you already have. $275 for the tune mailed to your door.
