Long story short, my HHR SS auto/trans is the 1st TURBO vehicle I've ever had = INSTANTLY HOOKED, even with all the restrictions GM set on the auto trans HHR's, etc. I've already begun a new from scratch engine build = another LNF 2.0L, but this one will be TWIN TURBO. I'm not new to the engine game, just to TURBO's. lol = yea, sounds dumb. I'm looking for good advice on a GOOD TUNE for my 2008 HHR SS auto/trans. I've done some research & know a few options I have = any other info would be awesome...


This may sound weird but if my engine didn't have a TURBO = i'd know exactly how to beef it up, as well as the suspension, axles, etc etc to handle what i have planned...

THNX IN ADVANCE...

 

There is a strong LNF tuner community. Prolly even more Cobalts than HHRs. Do some googling. Start w ZZP. Maybe RPM Motorsports in Mesa, AZ. Lots of larger turbos used. Never heard of a twin. Wonder if anyone's done TC/SC. If you're going for big gains , you probably need a custom tune from someone local with a dyno, not a canned one.

 

I appreciate the speedy response & info given = I'll check out the companies you mentioned. Yea, I got my 08 HHR SS auto/trans with 135,000 miles & she was in reliable condition. I'm thinking that a TUNE & replacing the TURBO with a new one would suffice = until my engine build is complete. I've already of course replaced a lot of the stock oem equipment to brand new replacements, etc = tank fuel pump/high pressure fuel pump/spark plugs & ignition coils/valve cover gasket kit, fresh fluids, new brakes = complete rotor/caliper/brake pad kit, etc.

As far as the new engine build = so far, I've only purchased 2 pieces = an engine stand, & a new LNF 2.0L engine block...
