Has anyone bought a set of injectors from this company boost lab for there conquest or starion?

Ok, installed a mechanical boost gauge in my cluster and after reinstalling cluster my speedometer is off significantly. I pulled the cluster out again and figured you could adjust the needle on the arm or somthin simple, but it just freely spins either way. It does work, and seems to be increasing at the proper rate only it is off about 20 MPH. Anyone ever run into this? When stopped my needle is reading well below 0mph. I did not cut into any of the circuit ribbons on the back I was very caref

I have a rebuit 17c turbo off a gmc syclone with just over 8k miles.Turbo was rebuilt at local shop. Turbine housing is ported. And wastegate arm is tacweld. I was running external wastegate. This turbo is a beast on this car. I can send you pics if youd like.The intake housing is red. Turbo housing black header paint. $500 shipped.    

Looking for a tan cloth interior. Straight line or checkered will work. Looking for a complete interior, front and rear seats, carpet and door panels. I will pay $1500 for a really nice interior.
