Just pulled a p0128 code
*thermostat code....probably from running the 160 unit that came with the kit....changing it out for the stock unit.
DO NOT take the thermsotat out, have them turn the code off. The cooler the engine is, the more power that can be made. Putting stock stat in can raise engine temps 20-30deg F which is equal too 2 deg's in timing.
It sounds like you have a leak, if you take the SC off, check the oring. Its key to put a lot of grease on the orings so they don't move when sliding the sc on.
If surging was on the highway, constant throttle, we can put a restrictor in the bypass line to slow its movement a little. I've come across this in a few.
Email us, when you have the SC off, what you see, [email protected].

the exhaust is all SW including cats...as far as the tune goes im dealing with jon lund directly. The combo that the truck has is a 3.375 pulley on the whipple and the full exhaust and thats it. As far as the short trims go they are very close together yes. I didn't wanna call whipple simply because i can manage on my own for the most part and i was confident i had a leak somewhere....turns out that two of the orings on the lower intake were damaged...they looked melted and the oring that goes under the blower had a flat spot that looks like it wasn't sealing also...so I'm pretty sure thats where the problem lies for now. Btw im keeping the stock thermostat for now, wondering if that had anything to do with the damaged orings.

i dont think i can use a smaller pulley on the supercharger with their tune...thats why i went the route i did....i was wanting to go built but the issue i have now is keeping me busy enough....lol
You can certainly run smaller pulleys with the stock tunes.....
Thermostat would have nothing to do with damaged orings. Thats from them moving during installation.
