Engine work and tune done by Brian Reckart of Reckart Peformance Tuning. A supporting vender here. Did an awesome job.


And last night Z06 front and rear sway bars.
Is that the 102mm size for C5s? So you're using the LS3/7 blade style MAF sensor as well?

That's a gain of 117 HP and 64 ft lbs torque. Pretty happy.
Sounds like a great matched setup, well done and congrats.

What strange maybe is ho much your pwr fell off stock... loks like it peaked around 5400 and then dropped. I dynoed my wife's 2k this week stock and it peaked at 5200 and held a flatline to 6000 revlimiter, with no drop at all. Do you have a factory ls6 intake? (2001-2004 model?)

Did you look at the dyno sheet? Horse power climbed all the way to 6377 rpms. Nothing fell below stock and we were shooting for a lot of midrange torque.

I think he was talking about the stock curve. The stock HP curve maxxed at 5400rpm then tailed off. Your HP curve on the new mods just kept going up... very nice indeed.

I'm comparing your stock dyno to mine, nothing else. The curve is on it's way down at the 5500 "x" vector line on the graph. Mine was completely horizontal at 6000 whereas yours is at about a 20 degree dive at 6000. That's all I was wondering is why. Lol. I know all cars run differently, just curious. Do yoy have a stock ls6 manifold (what year is ur car?), did you have a catback or any intake air filter or anything when you made the 307? Maybe the plugs were worn or old? Just trying to decide how "healthy" my wife's stock car is... Sorry for all the questions.

Ok gotcha. Thanks for the info. Prob the plugs breaking up up top with that many miles which makes sense.

Congrats again on the new power, wish I made 420+ rw!
