Cheers for the useful helps guys I will stick to buying the 100% overs
Should have read this first lol, 100s will be great then!

laggy and dirty are very subjective. Since my wonderful state has a $5000 fine for intentionally rolling coal, I am paranoid that a little poof as I pass a car will make a local LEO giddy to pop his $5k fine cherry... so I may say something is a dirty and others might think it's "clean"

100s without a doubt. Can be tuned to be just as clean as stock. Guaranteed.

Since Mark is making 650hp on that turbo with stock injectors and a 12mm cp3, 100 overs on a daily seems a bit excessive to me... unless you have plans to build the engine.



If you have a smaller turbo or aren't looking for the fastest spool, then you can be cleaner but who wants that I didn't set my truck up to be lazy. But as soon as you mention any soot output at all, people jump on tuning right away. If you want zero smoke, then put your DPF back on


You can lean into a 68 stg2r with 40s or bigger and keep it clean without a downshift. Been in a few trucks that Steve setup that way. Some of the best driving ones Iíve been in with that turbo. But again, it comes down to a factor of things if you want that. Some people donít believe it and thatís fine, I know it can be done as well as those that currently have the setup. I know chaves91 has done the same as well

Quantity of fuel to light a turbo does not mean itís the same across the board for 100s or 40s. The duration makes a big difference here as well as timing. Pilot injection also comes into affect and so does maf. It can vary greatly

Also proper converter has a lot to do with it.

Common sense would say to use 100s.

Sounds like you could teach Mark a lot, and he can try to tune my truck again after he's gotten better at it and you think he's ready.

obviously, I'm being a bit cheeky, and yes I oversimplified. My point is just that there's nothing wrong with the tuning to have a puff before the turbo eats. People right away want to jump all over the tuning and push their flavor of the month. Maybe I've been seeing too much of that on the FB posts and need to relax. LOL

Stick with a set of 100% and you will be glad you did in the future.

IF you do 100% make sure to have them done with LBZ tips not LMM's. LBZ's will run much cleaner and cooler than the lmm's will and you will be a lot happier with them.
