Sure. First and foremost, if you decide to go jb4, do yourself a favor and spring for the plugs (HKS MX45XL). Got mine on Amazon but they go quick. They will need to be gapped regardless of what any documentation says!!!!! The stock plugs are said to be ok on map 1 with a re-gap of 0.024 - 26. Good thing about the 2.0 is that the plugs can be changed in about 15 mins. 3.3 owners wish they had it that good. For me, no stock plugs. just want the best opportunity for "full combustion" and "safety". Keep the stock plugs for "just in case".
Don't go changing maps without logs and if you are not sure about reading your own, send them to Terry or in the "tuning" thread on this forum and have them critiqued. If you get a thumbs up, move to next map. If you are not going to go "all out' with mods, stay with map2. I have no dyno runs but I can tell you based upon logs and drive-ability, MAP 2 produces a very noticeable HP gain as well as torque. Enough to justify the JB4 in my opinion. I have only run 93 octane from day one even before attempting the jb4. MAP2 "Technically" only requires 93 octane but I know from my logs/performance that adding an "off the shelf" octane booster such as "Royal Purple" makes a difference in how smooth boost is delivered over the RPM range. This is only a 3 point octane boost but any additional helps. If you want serious octane boost, go for the "Boostane". You can order it online and has to be measured correctly.
In all, after the new engine, I only run the jb4 for the added "kick" when passing a$$holes on my commute but engine is running very well "stock". That being said, it will be your choice at the end of the day but I REALLY can't wait for my local dealer to get one of the 2.5's on the lot. They have an "Ascot" green MY 22 in the showroom but I still want to wait on the 2.5.
Thank you for all the info, this is what I needed to know. It really does run excellent stock. Any thoughts on Map 1?
