08 Mustang GT JLT CAI.

[mustangjonGT]

Well Im having trouble tuning blind for my JLT cold air intake. HP Tuners is awesome for GM, we got my friends vette to run faster. I was able to drop 4 tenths on my GT, but i know I can run faster with the CAI. Its the simplest mod. Would anyone out there have a sample tune for a CAI?

For the JLT CAI, you need to increase your MAF transfer #/min column by approx. +30% over stock. Once you do this, then fine tune the MAF transfer.

I'll try this. thank you.

[mustangjonGT]

Thanks I was able to get +/- 7%-9% STFTs by tuning the MAF. Man I could feel the difference with the JLT CAI. Now all I need are my gears installed and I'll be all set for now.

You can just email JLT and they will give you the correct MAF transfer for the intake.

[mustangjonGT]

I tried that. They didnt respond

[mustangjonGT]

This is the response I got from them today.

We don't do the tuning and don't work with HP tuners.
Sorry

Thank You,

Sounds like they are a helpful company. LOL! I will have to try this as I have a friend who changed his filter out on his S&B for an un MAF restricted filter and picked up another 8rwhp after tuning for the filter change.

Sounds like they are a helpful company. LOL!

Yeah tell me about it. Would still like to get the MAF more accurate, if I could only get the correct MAF Transfer for my CAI.

Thanks Eric, I've made it a TXT file so anyone can use this via the table import feature.

[mustangjonGT]

Thanks for this. I wasn't too off, but this made it perfect.

You may want to consider zero'ing out your MAF Compensation Table, FYI.
