Got the car re-tuned yesterday with the new setup. It is a 99 z28 so it has the crappy heads and is a M6 and has the stock 10 bolt The numbers seem a tad bit low to me but was wondering what others think. The numbers were 403/372 and the mods are as follows:
MS4 and supporting valve train
Fast 90/90 setup
lid & k&n
TR6 plugs and MSD plug wires
TSP 1 7/8" longtubes, TSP Y pipe, loud mouth 2 catback
Spec 3+ and steel flywheel
My old set-up was all the mods listed but had 1 3/4" longtubes, ls6 intake and 80mm. TB, and tr55's and picked up 16 hoursepower. So I was impressed on the gains it made. What do you guys think?

sounds good , numbers on the dyno not everything , my buddy with heads and cam pulled 389rwhp on the dyno but it insane at the street , he beats many cars like stock Z and +400 cars , i believe your car will pull very hard with your mods , i have the MS4 installed on my car now with fast 90 and t/b 90 , i'll re-tune my car till i order the injectors for 175 spraying , u should replace Tr-6 with TR-55 , are u planning for spraying with those plugs ? please post a graph
thanks, Mohammed.
thanks, Mohammed.

You'll be surprised how much you will gain with a decent set of ported heads.
From your current 99 factory heads to a good aftermarket will wake that motor up anywhere from ~40-6x rwhp![Nod](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_nod.gif)
Good results

Thanks a lot! Heads are deffinatly in the future. I have a 160 thermostat and a underdrive pully to go on the car so that will free up a little more power. Right now im working on a rear end and suspension so I can get the car to hook so unfortunatly the motor will stay like it is for a while.
