im going to build a biggass motor right away,, and plan on sticking with efi

do these chips work good,, i know BURN YOUR OWN CHIPS!!!!
but if all i ahve is a factory 305 chip,, and nothing to tune off,, how will i get the motor started!!!

motor will be a 400 sbc, with a fairly mild tappet cam, and probably stock heads for the time being,, somewhere in the 350 horse power 400 plus ft pounds,,, intake will be HSR or a custom sheetmetal one copying the one from tpis/ lt1 intake style

are these chips good enough? or is there a way i can get into chip burning without grenading my motor while trying to break it in? i dont feel like having a horrible A/F ratio and stupid timing on my beutiful pistons!!!

 

some people have had good luck with after market chips, but most have gotten better results by making their own.

this question would probably be better in DYI-PROM.
is your car still running? if so, now is the time to start to learn how to burn your own.
depending on what you go with & if you already have a laptop & go the cheap way, about $100.00 will get you the stuff to get started. if you go hog wild, AutoProm, bin switcher & remote switch, wide band O2, your looking at around $700.00 or so.

to burn your own chip, a stock chip for a 350 would be better to start with, from there you make a few changes for engine & injector size. it probably wouldn't be a bad ideal to pull some timing during break in to be safe.

 

I used him for the chip in my new engine.Its only temporary because i want to burn my own eventually.I just gave him a try because i was ready to drive my car after a year of saveing and building and he was affordable.I am happy with his work after 4500 miles and it appears he did a good job doing the things i asked for.If you have the extra money though I would go with Ed Wright fast chips.Also used him before and from what i understand he is one of the best if not the best,although twice as expensive.But as was stated you would get better results from doing your own.

 

Jamy at LS Racing Chips gave me an excellent tune (mail order..told him my combo, he nailed it on the 2nd try; that's WAY ahead of me learning to 'burn chips', although I will be 'rolling my own' chips soon!). Give him a call (330) 575-4162, tell him Bill sent you!.....then learn to tune on your own.
3rd Gens rock.. you can always build for power, but LS1's just don't have the "mean" look.
