mine hits the dyno in a few weeks with mods in sig bobo-any guesses? 
Hitting the dyno tomorrow for a tune, guesses??
Hitting the dyno tomorrow for a tune, guesses?? Hey all, after a year and a half with my cam swap, I'm finally hitting the dyno tomorrow for some tuning. Figured I'd see what everyone felt it'd put down. I'll start with the mods from the front to the back.
SSRA
SLP Lid/Bellows
FAST 90/90
FAST 36 lb injectors
Stock heads
Crane 224/224 .551/.551 112 LSA
Crane Gold roller Rockers
Crane Dual Valve Springs
SLP UD Pulley
Pacesetter Longtubes, going to a TSP TD X-pipe with no mufflers, dumped in front of axle.
Oh, and a little NX 100-shot (NX shots are measured in WHP if anyone doesn't know).
The last time I went, I was running the stock LS1 intake, and my baseline w/o nitrous was 365 or so running rich as hell, with some valve float too. This is on a Dynojet, by the way. I'm hoping to see close to 400 with the 90/90 and some good tuning. 520ish on the juice.
I also think I'm one of the only, if not the 1st person, to put numbers down using the Crane 224/224 which Ive been quite happy with so far.
So, what y'all think?

I got it because it was a steal of a deal on here barely used. So, for future expansion purposes, I picked it up.
I know right away I will get more torque than that...my baseline torque was 378 or so last time, no tuning.
Anyway, still waiting to jump on the rollers.

Valve float happened...again...still trying to figure out why. My best pull was 387/379, but the motor wasn't responding to ANY timing changes from the tuner. He said once I get the valvetrain gremlin's that have been plaguing me sorted out, he figured I'd get somewhere in the mid 390's and prolly similar torque gains.
