Yup, I agree with you on this. I'm pretty limited on facility but thankfully I do have a garage. Definately miss having my dad's shop to work in but my little two-car garage is going to have to suffice. Plus everything is going to come out through the top.

isn't it the mahle powerpack pistons that are junk? I have higher compression mahle pistons in my boosted motor, 10:1 on 72cc chambers...have had no problems so far and car is making some pretty good hp.

Is that .689@1.8 ratio? If thats a spec @1.7 then @1.8 you got .729! hope not...
Sounds to me like tuning issues...
The stock factory pistons are mahle castings and take more than you have given yours. Id be inclined to find a new tuner. Get a maffless tune done on E85.

Best of luck, as my will and wallet would have given up long ago. What kind of hp is the car making on the dyno? For what its worth, my car in sig has stock longblock and has 145,000 miles on it with 10,000 of those being boosted. Hope you figure it out, sooner rather than later...

Holy ****! Talk about bad luck. Good luck with everything bud hang in there! My 2. Cents run meth and get a different tuner . I've been making 600+ rwhp for 3 years on stock bottom end. 2 years with nitrous and 1 year with blower. Been running speed density the entire time.
