First off, I'd like to thank Jannetty Racing for giving me a good deal on a Magnuson s/c with their own *free* custom tune. Other companies I called would tell me they won't tune for long tubes or I would have to mail in my ECU (lame) for them to give it their special tune. Jannetty Racing EMAILS you a FREE custom tune and responds quickly to any questions you may have. I've been tuning the car with HP Tuners before, but will leave the forced induction tuning to the pros. I think JRE knows what they're doing

Ted was right too, I was giggling like a little school boy on his way to the toy store during the first few drives haha!

So, this next section is a very general observation of a few tables in HP Tuners Scanner while driving to work this morning, mostly for my entertainment.

Outside temp: 48F
Engine temp:190F

The kit relocated my IAT (intake air temp) sensor FROM right behind the air box TO inside of the s/c so it's reading intake temps (more than likely) before it's compressed **could be wrong**. I expected the air temps to be higher than ambient, but that was only the case by MAYBE 1 or 2 degrees. Sometimes it would read ambient temps (same as outside temp). After about 5ish seconds of being in boost (aggressive part throttle) the temps went up from 48 to 61 degrees. Again I'm not sure where the IAT is pulling this reading, but I'd like to find out.

The spark table was reading much lower than normal n/a (naturally aspirated) timing which was what I expected. At low rpm (around 2,000) full throttle, the timing was only 11 - 15 degrees, and up to 6,000 rpm I was only running around 15 - 18 degrees on average. Huge difference from what the n/a tune was. We tuned the LS1 in the Trans Am to run around 30+ degrees, n/a of course. I get it, more cylinder pressure = less timing. This is just a general observation because I enjoy this stuff.

Another thing to note was the Cylinder Airmass measured in g/cyl went from (before s/c install) .82 - .86 g/cyl (rough peak average) to 1.16 g/cyl (rough peak average)! For a quick referrence, adding Kooks long tube headers 1 7/8" primaries gave me about .4 g/cyl more air flow so jumping from .86 to 1.16 is a huge improvement.

Could anyone chime in on where the IAT sensor is pulling it's reading (before or after being compressed)?

First and only time to the track in my Camaro I ran 13.004 @ 111mph, can't wait to see what it does now

What are your numbers?????

Ted from JRE said I should be around 510 rwhp with LT's and stock pulley. They emailed me a tune so I didn't have to take it somewhere to put it on a dyno. I value the convenience and I don't like other ppl handling my car so it works perfect for me

You always here good things about Ted on here so you should be getting a good tune from him.

Correct. The IAT Sensor is located post-intercooler to give you the reading of the air just before it enters the cylinders.

Oh, and congrats on your purchase and welcome to the Magnuson Family.
