any h&s pukers ouy there

[shakes]

i have spartan tunes and run the 275 and 210 tunes,i have puked a handful of times with the 275 never with the 210 .i can beat the hell out of it on the 210 and never puke ,sometimes i will puke on 275 while driving rather calmly,with boost levels and egt's lower than what i see with 210,i am beginning to believe it may be a problem with the tune.my question is has anyone had puking issues with the h&s big tunes.i have not seen any posts about h&s puking anywhere,and there tuning is just as radical as spartan.if the h&s has not puked then why?could it be the harsh converter lockuo i seem to have with the 275,it sounds like my intake is gasping for air when converter locks up,i love the 275 as a daily driver but am getting tired of cleaning my engine.

If your puking all the time, your Head Gaskets are probably shot. Have you checked the Degas bottle cap to make sure it is the latest one? The newest one is all black with some writing, and the old one has a white sticker on it. The newer one clicks down much tighter.

Puking is caused from pressure in the cooling system pushing the coolant within the degas bottle out of the top around the cap. The cause of this is usually blown head gaskets, but in some cases its the EGR cooler flash boiling.

i really want to know if there are any h&s guys puking.i know alot of the spartan guys have had puking issues,but have never heard of a h&s guy puking.the tunes are very much alike .if h&s doesnt puke ,why?

Mine never has and I beat on it pretty good

What is the build date of your truck? How many miles have you had the Spartan tuner? Do you have EGR block off plates?

i have a job 3 08 harley i ran the 275 for about two or three months before the first puke and have puked a total of about 6 times,none being that bad(just a little spray around the cap)i purchased the block off plates but never put them in because i heard they might not be good.i cant understand why i would puke on 275 when i am not beating on it and can romp on it with 210 and nothing.anyone puke with the 250?i just got my liscence for the 250 and am thinking of running that,but i love the 275

Drive pressure is really high with these tunes. If your gaskets were weak from the get go, there is potential for puking. I see 71 psi drive (back pressure) max with the 275 tune. That is also what I see with the 310 and 350 tune as well. I puked before I got updated gaskets on my truck 11,600 miles ago. I have beat on my truck with the 275 (daily driver) and the 350 tune, and I don't even have pressure in the cooling system with the new gasket design.....also on stock head bolts.
