Is there a blow off valve installed? If so, is it before or after MAF and is it dumping into atmosphere or back into intake?

Depending on year make and model, some of the adjustable parameters aren't supported.
What type of modifications are done to the vehicle?

Assuming everything is sound with the engine, sensors and no vacuum leaks, you can try this. Because your stft are negative and your ltft are positive we really don't know which way to make the adjustment. I would start be adding 5% fuel. You would make this change in the MAF transfer function. This...

Obviously you want to be as close to 0% as possible but those numbers are still within specifications (10-15%). I'm not seeing any issues there. Are the trim numbers jumping around (fluctuating) or are they just staying solid?

What's year, make and model?
What is the LTFT values?
What is the MAF voltage at idle while LTFT are high?

Should be version 19 or higher. It's possible that v14-15 may be ok too but I'm not 100% sure. We no longer have the older versions to our disposal so I'm not able to confirm that.

To know what version you have there should be a small round decal on the interface box with a hand written number. If that's not there anymore then you would need to install the software and open it up. Once open you can go through the Special Forces questions to see if the IMRC question is there or...

Depending on how old your tuning kit is, you may or may not be able to disable IMRC with Special Forces. I know the last two versions did allow for IMRC deletes but older versions did not.

Unfortunatey, as it turns out, the CDAN4 calibration is notorious for being rich and is very difficult to set AF perfectly. It's going to require a lot of tweaking. The MAF meter plays a big role with getting this calibration running good (meter location, blow through, draw through, any pipe bends j...

Unfortunately that 127mph is not able to be raised. Have you looked into (or heard of) the OptiShift (now called US Shift)? http://www.usshift.com/usq4.shtml

I can email you the program but I'll need to know what name it's registered under.

Yes, no problem. Just install on the new laptop/pc and then provide me the 8-digit hardware fingerprint. Send to: snipertuned@yahoo.com. In the email, make sure you provide the name that the software was registered under.

What is year, make and model of your vehicle?

The Recon has been discontinued so it will not be updated to work with the 64bit OS. If you have version 23 of the tuning software (not Recon) then it will work fine with Windows 7, 8 and 10.

That's very high pressure. The software should not effect fuel pressure at all. If you want, you can email me the tune that you created and I can take a look at it. I can check to see if anything looks unusual or not right. If you want to send it, send to: snipertuned@yahoo.com. Be sure to include a...

That is pretty strange. Are you sure the injectors are 80 lb/hr?
In the software, did you select the 72 or 83 injector size? Have you tried both (make a difference)?

Yes, you would select 80 (72 or 83) for the injector size and 90mm Lightning. Just to confirm, the 90mm Lightning MAF you're using is still in the Lightning housing? You didn't remove the sensor from the Lightning housing and install into the intercooler piping? Are you sure the meter is good? If it...

With such big injectors I'm sure the performance tune is going to need some tweaking. Unfortunately, Special Forces doesn't give you full control. You would need the Commando software for that. However, have you done any of the fine tune adjustments in the Special Forces software? If not, try..... +...

As long as your laptop is 32bit then the Recon should be working. It's possible that there is something wrong with the Interface box. We'd be happy to check it out and replace it if necessary. No charge for this but I would need to get the Interface from you. Before sending it, make sure that you do...
