Help a newbie... bolt-ons ruined my car!!

[chao5.0]

The basics on how to do it, I've even seen them done on a fresh build before they dyno the engine before and after break in before doing power pulls.

It's fixed and runs great!!!

It had a dirty MAF... that was the problem the whole time...
Runs like a beast now!
Just wanted to give an update and close this chapter. On to the next...

Congrats, did you figure it out or did the shop? Are you going to try to reinstall anything now or leave it alone?

I figured it out... haven't taken it to a shop yet.
I'm reinstalling the bolt ons today to test it out...

Do not put that junk ass TB back on. Leave it stock.

Too late... I put the accufab back on as well as the JLT CAI.... ran like SHIT... Took the accufab off and ran just the JLT cai and it was worse....

Back to stock and runs good.

I've never had a car or motorcycle so finicky about bolt ons.

TB is useless on these motors and do nothing but cause issues.

Lesson learned.

Get it properly tuned

All of the tinkering you are doing, you need to install a wideband and educate yourself on A/F ratios, or LAMBDA. A wideband is cheap insurance and excellent for troubleshooting.

On modular motor, the tune is more important than the parts. You have to have both.

if the tune wasnt written with the JLT in mind its probably not good to run

I see that now... just wish LMR wouldn't have advertised "no tune required"

There’s a big difference between no tune required when adding it to an otherwise stock vehicle and loading a tune that’s supposed to be for a stock vehicle when yours is no longer stock
