TD61 Dyno on the 12th guess my RWHP!
do what arghx said, no crowds and spend all your free time checking everything over 2,3, 5 or even 10 times to try and find any issues you may have overlooked.
most often when i get a car for tuning there is almost always things that need to be fixed that the owner didn't realize. check your fuel pressure, do a TPS sweep, check your timing even though the FD timing is fixed to be sure your plugs are all firing and in the proper order. do a volume test of your fuel pump(at your peak pressure level, if your base is 40psi and you plan on pushing 20-25psi then check the volume by manually adjusting your FPR to 60-65psi), check pump voltage and under a load, and last but not least make a pressure tester to pressurize the intake to find any leaks you may not know are there. those are all the most common issues to start with, other issues can only be seen under a load on the dyno(generally weak ignition and voltage issues due to poor/old wiring).
20+psi is alot of force on the intake system, you may also find out that your couplers/vacuum line connections are inadequate for higher boost. superglue and ziptie your lines in place.
next common issue is improper wastegate and boost controller setup. double check all your connections.

Awesome advise!
I only have 1 vacuum line which is to my map sensor the rest is all AN fittings. I do know I need to adjust my couplers some more to make sure they are not leaking. My fuel pump will hold steady at 70 PSI so I don't believe I will have issues with fuel pressure but its def something we will be keeping a sharp eye on.
Actually the td61 is journal bearing.
The TDX-61 is a billet ball bearing

If thats the case it should have a designation for it.. like TD61r, to avoid such confusion. Just quoting what he lists on his website.
"This is the classic Garrett GT35R compressor section mated to a P-trim turbine wheel. This journal bearing turbocharger has a T4 footprint combined with standard size T4 turbine housings."

Did you even click the bottom link I posted right above your post
?There is a designation for it. TD61 journal bearing and TD61 Ball bearing.
sorry for the disapointment.... I got the car running right again after the injector but due to it snowing on the ground I decied to delay my tune till april can you say 3mm goopy seals, stud kit, xcessive oil pan?
