Superchips

Anyone try/using Superchips on their Jeep. Thinking of getting one for my 2002 GCL 4.7.

Re: Superchips

Let me preface and say two things: I'm a newbie to the group and this is my own opinion.

If it were me, I would spend my money on other performance upgrades. Aftermarket "Superchips" *must* meet all the same EPA emissions criteria that the factory chip meets. What this means is, for all your daily driving requirements this chip isn't going to do a thing to tweak the HP of the engine to any measurable degree. You may be able to coax a minuscule amount of added HP but only by subbing a cooler T-stat (no doubt sold as a "performance" t-stat) and/or feeding your ride with a steady diet of premium unleaded gas (did I hear the cash register ring??). But how can they claim the added HP numbers touted in the ads?....because that rating is derived at wide open throttle(WOT). WOT throttle is considered a sort of "emergency" condition and the EPA relaxes emissions requirements under this situation for the sake of maximum engine power...and how often are you, or anybody, ever in that situation?...ergo the relaxed restrictions and enhanced performance. The chip makers capitalize on this and freely tweak the engine in this regime of operation...with, of course, maximum grunt dependent on the 160deg t-stat and premium go juice. Other things the chip can effect are transmission shift quality and timing and torque converter lock up functions....none of these tweaks effect emissions and only work if you have (obviously) an automatic tranny. You will get the seat-of-the-pants feel your engine is putting out way more HP. Really, if the car makers could improve upon the chips they use don't you think they would? And in the end, unless you are in a highly competitive driving situation, the factory chips offer the intelligent compromises of a daily driven vehicle. A few years ago, Car And Driver magazine did a thorough test on the various chips and found they did exactly nothing or made such small increases as to be unnoticeable in daily driving....the increase was not worth the extra cost of the required premium fuel.

Just my humble opine. Good luck

Re: Superchips

Thanks for your input and yes I agree.

I did buy one and and ended up with the same conclusions you noted. I am using my Jeep to pull a 24' travel trailer and so far have found no advantage by using the Superchip, for towing anyway. After about a week of experimenting with it I put my jeep back to the stock mode. I am still using premium fuel only because of the extra load and a lot of up hill travel.

I did notice some difference in performance when I am not towing, but as you stated only at WOT. I saw nothing to speak of in daily driving. So far anyway. I have not tried the upper settings with 91 octane fuel yet(not towing anyway)
