TB mod
3" race pipe turbo back, no cats or exhuast

I was just wondering what settings did you guys put for similar mods. reason why is i'm not gonna be on the dyno for a while and was just wanting to get everything started and running safely when my downpipe/midpipe come in.

thanks

only a widband 02 sensor will tell

 

yeah, there is exact science to s-afc's you just have to work with them. You are the only judge of your car. Fatten up the mixture, run your car hard. Then slowly lean out the settings one at a time but be careful of "pinging".

 

Actually when tuning like this, a dyno should be the only judge of your car.

 

As Jason said. Sorry, but I really don't understand why you want to extract other people's numbers. Even with the same mods yours, or his, numbers will differ. WB Is the only way to go.

 

i understand fully, i am going to spend the time and money on dyno time, just not for a couple of weeks.

 

NZ, you know your right, I am sure that dyno is going to be impressed with you 200 rwhp especially when the 69' Camaro with the 8-71 megablower that was there before you was only putting down 600 rwhp.

 

Man I can't stop saying that NZ really know his ****!!!!

I've tried tunning my car with the butt dyno, it is really impossible to actually tell, know I have gotten better results tunning my car at the 1/4 mile track gotten it down 1 full second in some instances, but also both times I've tried to tune my car using the SAFC at the track, I'VE BLOWN MY MOTOR!!!!!! THere is NO way to tell how lean you are or how "safe" you are without a wide band O2 sensor, also I was only adjusting it by -1% both times I blew my motor. I'm not being an ******* just trying to get you guys to learn from my firsthand mistakes.

For my next motor I am keeping all the stock 550s, ditching the SAFC, and MBC, keeping my walbro and I'm only gonna run at 6psi-8psi (stock ported wastegate).

I should be more than safe with that setup

I'm going to make sure my next setup lasts me more than 4 months
