think im going blow through....but will i need to retune my car?

[((sr)) kelly]

like the title says.... im putting a T67 in and i think im going blow through... im running a sard racing bov and its impossible to recirc them..the turbo is already laggy enough... i dont want to be even laggier between shifts because of the excess fuel being dumped through the engine...


so if i got it tuned non blow through, would i have to get it retuned when i go blow through?

thanks

[bo2o]

what are you using to tune with?

[fromxtor]

I dont see why you would have to.

ive also heard that blow throughs kill mafs??

Biggest thing that will kill your maf in a blow thru is if the turbo starts spitting oil into the tract for any reason.

thanks...do you think i would have to get my car retuned if i changed over to it?

[heychris]

current theory over at KA-T is that moving the MAF to the cold pipe causes a lean shift in your AFR's. So you'll prolly need a retune, or changes to whatever AFC your running. Dunno if that's the case for SR's....Good luck, let us know what happens!

MAFS are sensitive to temp. Air changes its density as it expands and contracts with temperature and pressure, so under boost=higher temp=different reading

if its tuned they "kinda" work. - If anyone wants to know tho...

the stock plastic maf housing WILL LEAK - PERIOD.

You can glue it, hoseclamp it - etc. Or u can send it out to get it put in a metal housing like this.
