    Next week eh? Hmm... All I can think to say is good luck... I didn't even think they still made access port, where did u find that thing?

    Bigger turbos don't do well on stock tunes.. When I had a Jcw turbo on stock tune it would still pop into limp like that...

    I've been trying to get a big turbo tuned all summer. The current tuner is taking a break because he's pissed off :mad2:

    I have a 43/56 hybrid turbo on my '07 S. On stock tune it does well. No limp mode, when I load up the boxed Stage 2 Manic tune set to Map C it does very well. I have had no problems with mine. I have yet to get to the dyno however to see the "number". I'm not inclined to make my car a number.

    That being said, anything AP tune related I would steer clear of. Too many issues have been identified over the years. I have no experience with JMTC so I can't give you input there.

    AccessPort has also been called AccesPoop by some users.

    You want a bigger turbo, forget the AP canned tunes --- you need a custom AP tune, and I don't believe there's anyone out there doing them anymore. My suggestion --- install the turbo, then get a Manic tune --- he can tune for up to 30PSI with no cel's. The AP can still be used for code reading / clearing, data logging, etc. It's still a great tool.

    I have had the AP on other cars and they work great. But I agree you will need a custom tune on it. Or you could sell it over on the other site and get a Jan tune.

    Manic Tune .... LMAO

    More like maniac tunes, how many more cars have to blow up until they finally go under? I know they are huge on the fantasy world of LXM and Facebook but then again its still Facebook.

    I have an Access Port and I really like it. You don't need a custom tune, if you have he stock turbo. The canned tunes are conservative, so there is no worry that you will blow up your engine, it still gives significant horsepower gains.

    Thanks guys. I ended up doing the track day on stock tune. Would go limp mode if I tried ANY AP tunes.

    I can certainly see the dislike for it. On the street the torque rush at lower RPM is great. But top end barely feels faster than stock. I had it on for an autox and actually found the car easier to drive thereby faster on stock tune.

    If I could find a tuner that will do an AP custom tune that would be great. I'm skeptical on Manic just because it's a significant sunk cost and I doubt the engine's longevity after. For street and maybe even drag strip use I'd be less skeptical. But 20-30 mins of abuse at Sebring or Homestead...

    Crazy to see the difference. I'd be 42/56.

    I guess I should put it on with the expectation that I'd have to get Manic tune (most conservative, wouldn't even get a switch). But if it runs just fine I'll leave it as is.

    Yea it's old AF and closest thing I find id info on the JMTC version.

    But if the tune file exists I just need to find/buy it.
