I /m having the vortech s/c with JWT cams installed on my 350 5A/T. What results should I expect on the dyno given i already have nismo headers, borla TD exhaust, and test pipes. Also, my shop will be tuning the s/c with the R4 software they got from split second. I have been reading on threads that with the right uning with this software, you can get up to a 20whp gain. Any opinions would be great. I cant wait to pick this beast up.

 

I have a similar configuration in the G35c and I am getting 390 rwhp. Just be SURE they get you’re A/F down to mid 11’s (no exceptions) during boost otherwise kaboom.

 

my tuner got 61.1 rwhp more from retuning, and 49.x rwlb-ft TQ.....

well worth the price of admission, but prolly not the rule (nor the exception)...

like DFW stated, shoot for 11.25-ish for a/f, even if they can (easily) net more peak power by fueling to 12-ish....

you wanna go fast, but for many, many days and weeks and months.......
