As many of you know I had my Stillen Y-pipe installed on my 95 SE AUTO yesterday. Lastnight using my VERICOM PERFORMANCE Computer I was able to determine that I had gained approx. 10.2 FWHP which would translate to about 15 HP at the crank. The difference it has made is incredible feels like when I installed the JWT ECU, big differce that you can feel !!!!! The car is NOT that loud even when I am at WOT. My engine mods at this time is Intake, JWT ECU, and Y-Pipe. With these mods I have gained approx. 23.8 FWHP from my baseline test of completely STOCK according to the Vericom computer which would be about 30 hp at the crank. Not bad in my opinion. Let me know what you all think, comments, etc. Thanks.
That's about what other's have gotten ->
the only thing is that pretty much all the common normally aspirated mods you can do from here on out won't gain you much. The RT cat and a cat-back exhaust might be worth 7 HP at the wheels at most, but the gains are more at the higher rpms only so it won't be so noticeable. You have the #1/2/3 top-gaining normally aspirated mods right now...and they don't add a whole lot of noise either. Personally, I'd stay right where you are in terms of engine mods, unless of course you have the money for the S/C kit.

Doesn't the 95-96 Max come with like maybe 5,6,7 more hp than the 97-99. I thought the cam was diferant or somthing. Good power gains man!!
