I just installed a greddy turbo and got it tune today and was only able to make 270whp. I was wondering what i can do to make it hit at least 300whp because i see a lot of people on forum hitting that with a greddy kit. right now i am just running basic stock no exhaust or anything yet.

What psi are you at? It's easy, turn up the boost, or get a test pipe. If you have the money, get a full 3 inch exhaust with it.

Who tuned it and what type of dyno was it?

What were you tuned on? What's your downpipe and exhaust setup?

what does a stock s2k on that dyno produce? you bought a greddy kit, dont get greedy with the numbers

sorry, had too. real talk though, what other mods you have?

A high flow cat or test pipe will open up the top end. Water/meth injection will let you run more timing also, and keep the exhaust temps down.

also how hot was it when u took it to the dyno? i just had mine tweaked and i toped out at 274 on my sos kit but it was damn near 100 degrees and humid as crap. i wasent hitting full boost :/

You'll quickly find that temperature/humidity outside greatly affect how a boosted car performs. You'll hate having a boosted car in the summer b/c it'll just feel slow and in the winter it'll be awesome. It's just something you have to get used to.

Envied

That is a true statement. When I had a greddy kit on my car, I was making 285rwhp on the dyno. Took it to the track and it ran 13.5@103 with a 2.0 60ft. Ran against a couple cars later that night, that were at the track... They ran 13.5@105-106.. I put a consistent 2-2.5 cars on them from a 40 roll to 120. Humidity and temp played a big roll with that Greddy kit. The bottom line is, that turbo kit is under engineered for the breatheability of the F series motors...

270 is about right for a greddy kit I don't see and issue. Also the kit is what it is a fast spooling easy to install turbo kit.
