I was wondering...... I have the 305 tbi L03...i am going to swap it out but i want to mod it..... should i stick with tbi or go carburated? i have no idea how to burn chips and don't wanna buy the stuff to do it.... waht do you guys think? thanks

If you dont want to get a well tuned engine and get better cold drivability as well as better fuel mileage then go with a carb!! If you do then get into chip burning or emulating-not using chips then stick with tbi efi. Just my 2cents

LS1

LSX block, heck jet engine!

na stick with the TBI, then gradually learn how to tune it. That's what i'm doing. don't understand anything about tuning even after reading the 900 walk throughs that link to the other walk throughs that never answer another's question. I think the crappy DIY PROM sticky's might make me go carb.

i agree with you..... i don't understand the DIY PROM tuning stickies...... no one on TGO seems like they want to take the time to help you learn it yet they yell at you b/c you don't get it....... whatever..... i could do it if i was shown how to do it.....

I totally agree!!

WHat i would like to do is intake manifold, headers, TBI unit, cam and heads at least on the 350 i'm gonna get but i can only do like headers without having to burn chips..... seems too hard to do.....

I would go with carb, its just so much easier to work with.

Read through the "free tune" thread at the top of the forum. This is my baby step by baby step guide to tuning. If you still don't get it, you HAVE to go carb. TBI is like a very complicated carb with over a 100 jets, without chip tuning you can't change a single jet.

You wouldn't buy a carb that you couldn't change jets in would you? Would you buy one that was setup for a stock 305?

There is no shame in "not getting it", but don't fool yourself and slap on parts blindly with the idea that you can simply order up a "custom" chip to make it all work, it just won't happen. If you are doing anything more than exhaust either learn to tune or plan to swap to carb and be ready for all the negatives that come with them. Carbs are a beutifully simple way to put fuel into an engine, once you learn the basics of how to make them work well on an engine you'll quickly see the power of FI when you have full control of it. It's really a learning curve, you can't run before you can crawl.
