Or did he say "The AFR's you described are normal, BRO"?

If TTP did an email flash on your car, talk to them. I have had tons of work from them, along with 5 or 6 tune sessions. Trust me, Scott knows what he's doing. Did you send him them logs? If not send them to him. If he says its fine, express to him that your feel that its to risky, even though there is no knock, and I'm sure he'll work with you.

He is a great guy, and he replies quickly. I sent him my first logs that lead to this new tune. I haven't sent him anymore logs because he wants 4th gear and the state cops are picking up on the part of the highway that I do my higher speed pulls. Maybe I will have my friend do a pull while i sit in the passenger seat lol. I really wanted to see the difference between his and al's flash, so I could figure out how different tuners tune.

I know firstshand how different their tuning abilities are because I have dealt with both of them. There is definalty a difference between the two, and my preference is obvious.

1st, 2nd, and 3rd will typically be slighty more lean than 4th.

Where are you located? I do a pull down the highway. I aint scurred

lol, I ain't scurred normally. I just know this time of the month there seems to be a lot of cops on the highway. And at night you can't see them until you see lights, bastards, jk. I live quite a ways away from you in New Mexico. I will probably stay with ttp or jestr next time as soon as I get off my **** and put the parts in that are in my garage.

This is my mapping. I really do not understand why people do this. If there is not enough trust in listening to your own tuner, then you should be tuning the car yourself as you become your own expert.

I give customers a specific circumstance to datalog. Why they choose not to listen and try to be the experts themselves is beyond me.

Your afr for a 2nd GEAR pull may even be on the rich side. 3rd gear will be 11.5-11.6 and 4th gear 11.3-11.4

If you cannot trust enough in a tuner to listen to their advice, an eflash is not for you. You should be tuning the car yourself as you have deemed yourself to be more knowledgable than the tuner at that point.

Stop trying to be the expert Jeff, you are well aware of my capabilities as seen many times.

This is a PRO tune, not a BRO tune.

You are a tuner.

Could you elaborate on why you have him in the low 12's? I know his power and torque will be higher with that a/f than with a 11.7 ...the main issue is if he gets bad tank of gas or something else.

To achieve the desired afr in a long gear 4th, the short gears run leaner.

Stick your hand in the oven at 450* for 2 seconds.

Then stick your hand in the oven at 450* for 15 seconds.

Let me know what the difference is.

OK.

So do you include Lean Spool disable to combate the lean long 4th gears? or No...
What's your take on Lean Spool Disable?
