Howdy, I was wondering what is the opinion of y'all regarding mods on the 155 Hp 2.2. Is there enough benefit with the old air intake and exhaust to justify the cost ? I am only seeking performance gain with a side benefit of higher mpg 's. Opinions? Or any other reliable performance mods you like.
Thanks

 

The real benefits of performance intake/exhaust combos can be debated from here to eternity without doing a dyno pull or two. Based on the old "butt dyno" the GMPP intake/exhaust combo on my 2.2 & 2.4 gained me something and it wasn't much more mileage, I'd say a few hp were liberated but nothing vastly spectacular. But the aggressive sound and a bit more punch off the line are worth it to me, something to consider is the Trifecta Tune, the folks here who've invested in it seem to love the results.

Here's a link to Trifecta for you....

First leveling or lowering springs, then OTTP Street Bar, then a Tune..

was the sway bar a group buy? is it still on? Thanks

 

The copier of that bar in post #3 quit making it.. Google it & the word "warp" you will see why

 

I think I noticed a set of the Rear Lowering Springs for sale in the Classifieds!
