Buick vs Ford 2017

Jason, I've been going over Erics SD2 vid. I understand what he's doing...and it's a crapload of work...and time consuming. I have a PL file you told me about...and I'm gonna tweak it to learn.

SD2 is for someone that loves to tinker. For someone like myself it wouldn't gain me anything...oth er than a full out max boost run with the MAF being removed to remove a restriction. I already know how far I can push my fueling. SD2 is interesting... to say the least. I'm definitely gonna be going over SD2 files.

Since you don't drive the car on the street, you'd be tuning for that very narrow rpm band.  You do have to tinker quite a bit but nothing like the xfi software. It's a not a whole different animal but it does have it's idiosyncrasies that need to be learned that don't cross over from SD2 to XFI

The WOT part is easiest. It's coming up on RPM to WOT that's the trickiest and time consuming. I can see how guys blow shit up. I have the advantage of knowing where from a fueling standpoint my engine makes peak HP. Rewind a few weeks ago. With a big temp/humidity change I had to completely retune my car. Two adjustment runs and the car went 7.1x in first round eliminations.. .and I wasn't pushing the car and that was on an easy 1.8 launch on 23 PSI on a fat tune. SD2 is really cool...but when I hit the track I'm there to race...not to tinker. One practice pass...make my fueling adjustments... and it's on. You're a smart guy...and given time you'll be just as quick making adjustments with SD2 for tuning.

Nothing wrong with that. Real salty for a street car with ac.

I think the SD1 was better than the 2.  Kept things relatively simple but gave a lot of possible tweaks.  After initial playing, there are only about five things that I adjust.  The 2 was for the nerd market that thinks you have to be able to adjust like an aftermarket system.  I quit the nerd market a few years ago

When a 10 flat car with a 5.7 chip won't go any faster with XFI tuned by one of the very best...then that's all I need to know. Looking at the underhood of my car is a sure fire cure for insomnia...and I'm good with that.

I remember the 9.5 car that was guaranteed to go two tenths faster and it took a year before it went any faster...tuned by the best.  I also remember all the 11-12 second cars that never went faster as well.  there is a difference between marketing and measured performance.  People seem to refuse to learn from history.

The funny thing is that we often have someone tell us that you can sell your old stuff and basically pay for the new, but, they never mention the cost of professional tuning and dyno time that comes afterward...we be preaching to the choir!  LOL  There is always someone that thinks it will solve his problems and give him the performance he thinks he should have.
