Realistic gains from these mods? So i have a Catless Hogan DP, SLP Catback, and a CAI Intake on the way..Once I get all these in, I plan on getting a tune..Do you guys think I could get 25 hp out of these mods?
Thanks
Thanks
I doubt you'll se 25, but maybe. I never dyno'd mine stock so I have nothing to compare it to.

yes, with those mods and a tune done right, you could see 25hp/tq gains...

If you put down 255 and gain 25hp then you'd be making 280whp. Sorry but most guys can barely hit 270fwhp all modded out! Come to think of it.. I bet a catback and intake will only net 5fwhp. The rear exhaust manifold outlet is only 2 1/2" and the Intake neck is super restrictive. You will feel a diff though.. so no worries. 1.8 rockers make the biggest gain.
One thing of interest though, is that our cars do not dyno well. Stock LS4's run about 98-99 through the 1/4 and with a intake, exhaust and tuning they will go through at 102-103. Adding rockers with raised shift points 6100-6200 (5940-50 stock) will increase that mph to 105-106. Tb spacers seem to add part throttle tq with no increase to peak numbers. I think that removing the tq management is what helps boost the mph
Each MPH you gain is about 10 hp at the wheels. So I guess you will see 25hp at the track but not on the dyno. Dynos do lie. I'm confussed by this at times myself.
Good luck and do get tuning or else you will lose power. trust me!

Thank David. I'm sitting here thinking...**** if I was supposed to get 25hp before headers I've been cheated! lol
