• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

hi was just wonder what tha gains would be i have 2.5 dp with plog and am thinking of ported rear mani i know the rear isnt very restrictive but would i get al least 5 hp
 


why not just go with headers. Really you need do a u bend delete. Also search for safetly moding your 3800. This will help you out it's like the gp bible.
 
If he has a 2.5" DP I bet he already has the U-Bend gone. IMO, I'd get a ported TB, a tune, 180* T-Stat...do new plugs and wires...maintenance sh1t never hurts...Do ER Rockers too...it should put your car in the 14's. Or just get it over with and top swap the car.
