HF's are multi port. he just has a dx. same pistons in all of them though. 10psi on a good tune is pretty much the max.

sewell94 keeps telling me about this stock block y8 he tuned to 16psi. been running strong for a couple years. its all in the tune.

Thanks for all the help guys. and thanks for not ripping on me. I've read a lot of threads were people basically ripped on someone for asking a dumb question and they never answered the actual question.

Get a wideband.

we can tell who deserves the help and who are just douche bags.

you are ok.

how are you controlling those bigger injectors though?

I planned on bringing it to jotech in garland, texas and getting Kenny to work his magic.

what are you doing to control them now though?

Uh... nothing. I'm not driving the car all the time. I just got everything together and took it for a couple of testdrives to see if everything was sealing properly. Havent gotten on it hard though.

i like your username...your car doesn't make sense...and boosting with no fuel management? no fmu/crome/uberdata?

expect it to smoke in no time. running 310's with nothing controlling them will wash the oil from the cylinder walls and it will be smoking once everything is worn out nice a good.

yea put the stock injectors back in untill you get something to controle the bigger ones..

oh and dont boost untill you get it tunned... ;)
