they don't do a whole lot of tuning of the wbodies there at LMT.

I know they do mostly corvettes but they are the only performance shop in my town that really deals with aftermarket parts. I cant really do mods myself since I live in an apartment with no garage...
He suggested i maybe check my fuel pressure to see if that is where it needs to be. I also thought I have bad O2 sensors since I am using the originals in my new exhaust system. I just hate to waste more money on parts that are not the problem.

Another tuner who just regurgitates what the software says without basic fundamental understanding of how things work :(
If you were pegged at 4500 rpm your dyno curve and AFR curve would look much different.

I was thinking the exact same thing. I even said that it looks like the commanded AF from the PCM and not the actual. Because there is no way in hell it would be that flat and on the "lean" side. Even he was suprised he didnt see the AF curve rise after the injectors maxed going up to higher rpm.

1) you're kind of wasting your time there. just stay away from them. unless it has an LS in it, they're kinda useless for tuning.

2) you don't need a tune. you don't have anything done to the car. just drive it.
 
Well my car is getting 12mpg ish and is a complete bog in the 1000-2000 rpm range so I know I have a fuel trim or sensor issue. Not to mention the 160whp is low for HV3, and Headers.
 


Just buy hpt and do your own tuning with help from guys on here...lots of info on here and the hpt forum...there is hpt and dhp forsale in the classifieds

The L67 has lower compression and it only makes like 6psi of boost. How much more do you think it should make out of a roots blower on 6psi?

Everything about this video is terrible.
 
I thought L36's dynoed at like 140ish so if l67 did 200ish then it would kinda make sense, I think im confusing myself or completely wrong lol
Edit saw snowflakes post, makes sense then. Cuz the m90 is kinda poo.
