Tell me what you think

I have a 99 wrangler. 2.5L. I know engine swap. Not wanting to do that. So far jeep runs good but I wanted a little more. Posted befor and got a little more of a idea. But I like the 2.5l and here is what I've done. Added throttle body spacer and cold air intake. This has improved performance. I've noticed going up hill about 5 more mph. Today we are swapping clutches I got a shutter when I take off after engine is warm. My thinking is a warped flywheel ? I read somewhere by adding a heavier flywheel will increase torque? This true? Also on a v8 bigger carb better performance. So bigger throttle body should also work? I'm new to a jeep. But a motor guy so that's why I'm making the most of this 2.5. Any other thoughts for me

Most anything you do will be placebo at best. Your engine can't handle any more air or fuel. The only way intake/exhaust upgrades work is when they are the bottleneck. In this case your engine is the bottleneck.

The flywheel will help some. It will even out the power band a bit. Larger throttle body won't. It's not a carb only an air regulator. It's sized corretly as is.
