I am from Philly and I am wondering which is the best protuner in the area.. I plan on taking a trip to whoever is the best in the area.. Anyone with any good suggestions? I have a lot of things going into car (03 wrx).. Here's a list:
2.5 STI Block, Wiseco Pistons, Eagle rods, ARP Head Studs, Ferrea oversized valves with port and polish on the heads, stage 2 crower cams, titanium crower valve sprting and retainer set, perrin fuel rails, greddy timing belt, tgv delete, sti intake manifold, sti pinks,txs turboback exhaust and uppipe, sti crankshaft, etc.. do you guys think that it can handle all these mods? I also have a streettuner.. I am running off stock turbo and intercooler though.. any suggestions any one? Answers would be greatly appreciated.

precision tuning in new jersey man. thats where most people from our area go. they also have a website too. theres also one in maryland called agile, they have a website too. both do protuning. good luck where from philly are you from?

+1 for precision
With that long list of parts, I'm thinking that you're looking at a VERY custom map, rather than some minor adjustment to one of Cobb's OTS maps. Hopefully, the guys at Precsion can get you started with the street tuner.
