I just installed a turbo XS h34 universal blow off valve , and im not sure if i need a retune, right now i have 3 spacer in front of the spring. it runs a lil' ruff at idle.... does n e one else have this bov, also u really can here ****....... do i need to retune....... i didn't even weld it but i figure that there is not enough preasure to blow it off, its on very tight right now......

 

If your car is idling rough with the valve installed it is probably due to it being slightly open at idle.

I recommend adding additional shims until it idles better. If it does not idle correctly after adding all 6 shims. You may need to use the stiffer spring. If one was not supplied to you please contact me at the number below.

Thanks,

yea i got the spring, so u suggest using all the spring, correct?...... i mean i think adding all prolly might make the diff..... i'll try thanx for the help

 

I didn't put any extra washers in mine and worked great as is.

 

so no washers then, i guess i will try that first, your sound n e diff or no?
