I seem to have a problem ive done several modifications to my Rx-7 (93), when I bought it came with Blitz intake and HKS exhuast (super dragger) ive modded it alittle since then.. ( M2 downpipe, greddy turbo timer, greddy innercooler piping, greddy intake piping, and changed the secondary turbo soleniod) I am still boosting 10psi then drops to 6-7 then raises slowly when I am at full throttle..

I think I have a boost leak at my STOCK Y-pipe though I am not sure, could I take it anywhere to have it checked maybe a Diagnostic? would that show where the boost leak is at? I have replaced all the stock non-solid parts so I strongly beilive that the leak is at the Y-pipe for some reason a sorce said I should be boosting at least 12psi now with that DP installed and hard pipes.

Thanks
