What horsepower mods have you done

[36382mm]

Getting the itch for more power and trying to see what people have done. Looking to do a pulley and tune on 93 pump gas (e85 not readily available) Who did you use for tune? What size pulley? Should I be looking in another part of forum.

Great topic! I'm thinking of doing the VMP OE drag package with the 81mm IC brick, TB, 2.75" pulley and tune. I already have the JLT intake, and also have no access to E85. Not looking to go crazy as our Arizona 91 octane is awful.

Was the JLT by itself noticeable? Seen some graphs that say It gives 30-40 wheel...

That’s a can of worms you don’t want to open. Yes the JLT is proven to add power in an apples to apples comparison. Will you feel it on a 760hp car? Not likely but it’s a great supporting mod should you wish to do more.

It seemed to make some difference, but was nothing earth shaking for sure.

I noticed it I guess...I don't believe its worth 30 to 40 to the wheels. It was already mentioned, its a can of worms type subject.

I'd like to be around 750 to 775 rwhp . Would rather not do injectors or a boost a pump. I'm thinking a 2.75 pulley and tune plus the cai should get me there.

Think I saw a Palm beach dyno vid of that exact setup... it was like 757 at the wheels 610-620 torque, somethin around there.

I built my own cold air, my own cat delete and res delete, 2.8 pulley, tune, and 15 inch wheel conversion and 325 50 15 drag radials. Haven't dynoed it to know the output.

How much boost do you see with the 2.8 pulley

Anyone here ever use Livernois Motorsport for tuning.

14psi at 7500 but then if I run it all the way to 8400 it hit's 15.

I used Livernois for my 2021 GT500. Zero issues. All I have is a CAI and their tune.

Any chance you had it dynoed?

Did you go there for tune or was it just plug and play with their programmer?
